Book excerpt: Troy Townsend's thesis explores the structure, energetics and activity of three inorganic nanocrystal photocatalysts. The goal of this work is to investigate the potential of metal oxide nanocrystals for application in photocatalytic water splitting, which could one day provide us with clean hydrogen fuel derived from water and solar energy. Specifically, Townsend's work addresses the effects of co-catalyst addition to niobium oxide nanotubes for photocatalytic water reduction to hydrogen, and the first use of iron oxide 'rust' in nanocrystal suspensions for oxygen production. In addition, Townsend studies a nickel/oxide-strontium titanate nanocomposite which can be described as one of only four nanoscale water splitting photocatalysts. He also examines the charge transport for this system. Overall, this collection of studies brings relevance to the design of inorganic nanomaterials for photocatalytic water splitting while introducing new directions for solar energy conversion.

Available in PDF, EPUB and Kindle. Book excerpt: Solar energy conversion is considered one of the most promising renewable energy solutions for replacing fossil fuels and easing global climate change. Developing a cost-effective technology for solar energy utilization to compete with market grid price is among the top priorities of our scientific society. Photocatalytic water splitting, which utilizes solar energy to produce carbon-zero hydrogen fuels from water, holds great potential towards achieving this challenging mission. Photovoltaic (PV) devices, for converting solar energy to electricity, continue to witness technological advances in the 21st century. This dissertation is dedicated to the advancement of photocatalytic water splitting and photovoltaic technologies, including the search for inexpensive photocatalysts with high efficiency, the fundamental understanding of photo-induced charge separation processes and the advanced instrumentation for probing photovoltage generation on the nanoscale. Chapter 2 starts off with the effect of quantum size confinement on the photocatalytic hydrogen production by CdSe nanocrystals. The particle size of a well-defined CdSe nanocrystal series is systematically varied, and their size-dependent conduction/valence band energetics as well as their photocatalytic hydrogen evolution rates are characterized in details. This allows the construction of a quantitative correlation between particle size, energy level and photocatalytic activity for CdSe nanocrystals, following Butler-Volmer electron-transfer theory. Chapter 3 transitions into the study on WO3 photoanodes for photocatalytic oxygen evolution. The activity of WO3 photoanodes is greatly enhanced via an in-situ doping by electrochemical reduction. Investigations show that the moderate reduction boosts carrier concentration and conductivity in WO3, consequently an improved charge collection and an increased photocurrent response. This activation strategy is also proven to be applicable to other WO3 systems with a wide range of particle sizes. Chapter 4 introduces surface photovoltage spectroscopy (SPS) as a powerful sensitive technique for probing photon-induced charge separation processes in photocatalysts and PV systems. Calcium niobium oxide, a wide bandgap hydrogen evolution photocatalyst with a well-defined surface morphology, is selected as a model material for understanding the photovoltage generation and charge separation in photocatalyst system via SPS. Systematic studies reveal the dependence of photovoltage on photon wavelength, light intensity, defect density, film thickness, ambient environment, substrate property, and the relative Fermi-level difference at the interface. Chapter 5 continues the application of SPS technique for understanding charge separation in CdSe nanocrystalline films for inorganic-/organic- hybrid solar cells. Surface ligands on CdSe nanocrystals are found to have a dramatic impact on the photovoltage responses from CdSe films. The replacement of native ligands by halides and amines leads to electron traps at the particle surface. Chloride, among all halide ligands, is indicated as a promising short surface ligand for good photovoltage response, whereas bromide and iodide are found as detrimental hole traps.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Solar energy conversion has the potential to reduce society’s dependence on fossil fuels and to diminish the harmful effects of climate change by generating clean power from the sun. The process of solar hydrogen production by photocatalytic water splitting uses solar energy to generate hydrogen fuels from water and has been explored extensively in recent years as hydrogen is considered a very promising candidate for a clean and renewable solar fuel. However, only a limited number of earth-abundant photocatalysts have been shown to be active for visible-light driven H2 evolution. New advances also continue in photovoltaic (PV) technologies such as hybrid solar cells, devices composed of inorganic semiconductor quantum dots (QDs) mixed with organic conducting polymers. This dissertation will focus on the application of Surface Photovoltage Spectroscopy (SPS) to study photochemical charge transfer processes in nanoscale photocatalysts and on the characterization of charge transfer dynamics occurring in inorganic-organic hybrid solar cell films. Chapter 2 explores a photocatalytic nickel oxide nanoparticle system modified with platinum co-catalyst for photochemical hydrogen generation. Nanocrystals of NiO have increased p-type character and improved photocatalytic activity for hydrogen evolution from water in the presence of methanol as sacrificial electron donor. Surface photovoltage spectroscopy of NiO and NiO–Pt films on Au substrates indicate a metal Pt-NiO junction with 30 mV photovoltage that promotes carrier separation. The increased photocatalytic and photoelectrochemical performance of nano-NiO is due to improved minority carrier extraction and increased p-type character, as deduced from Mott–Schottky plots, optical absorbance, and X-ray photoelectron spectroscopy data. These results are relevant to the understanding of NiO-containing photocatalysts and to the electronic properties of nanoscale metal oxides and junctions. In Chapter 3, surface photovoltage spectroscopy (SPS) was used to study the intrinsic charge transfer properties and surface states of thin films of thiol, amine, carboxylic acid supported CdSe QDs on indium tin oxide (ITO) in the absence of an external bias or electrolyte. On ITO, the QD films give positive or negative photovoltage signals (-120 to +350 mV) under sub band gap and super band gap excitation (0.1 - 0.3 mW cm−2), depending on the ligand type present at the QD surface. Experimental photovoltage values are found to correlate with the LUMO energies of the CdSe QDs, obtained from the electrochemical reduction potential in tetra-n-butylammonium hexafluorophosphate electrolyte at unadjusted pH. This suggests the possibility that the built-in potential of the ITO-QD Schottky contacts is controlled by the electronic properties of the ligands. The findings shed new light on factors controlling photochemical charge separation in films of ligand-stabilized CdSe QDs. Chapter 4 presents a study of a nanoscale doped perovskite photocatalyst, chromium-doped strontium titanate (Cr:SrTiO3). The Cr:SrTiO3 nanoparticles form as well defined cubic-shaped nanocrystals with a mean diameter of 43.5 nm (±18.8 nm) and have homogeneous composition. X-ray photoelectron spectroscopy (XPS) and X-ray absorption near edge structure (XANES) analysis shows that Cr:SrTiO3 particles synthesized at high temperature contain high concentrations of Cr6+ trap sites while hydrothermally synthesized particles contain only Cr3+. SPS data shows that photogenerated charge carriers from Cr3+ donor states can drive photochemical reactions (e.g methanol oxidation) at the particle surface and that those reaction rates are increased by previous light excitation of the film. SPS also shows a dependence of photovoltage magnitude on substrate work function that is explained by the built-in potential (V[subscript bi]) at the film-substrate interface. Photochemical hydrogen evolution experiments show rates of up to 85 [mu]mol/hr (1.56% AQE at 435 nm). Rates are strongly dependent on solution pH, Cr doping %, and particle synthesis method. A mild NaBH4 reduction treatment was shown to increase photocatalytic activity in Cr:SrTiO3 and decrease its Cr6+ concentration. Surface photovoltage spectroscopy (SPS) also reveals an anomalously increasing photovoltage with magnitude greater than the band gap of SrTiO3. A model is proposed to show that the unusually large photovoltage, as well as charge separation in Cr:SrTiO3 in general, can be explained by a light-activated ferroelectric effect that causes ordering of electric dipoles in the non-centrosymmetric Cr:SrTiO3 unit cells.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The photochemical water splitting reaction is of great interest for converting solar energy into usable fuels. This dissertation focuses on the development of inorganic nanoparticle catalysts for solar energy driven conversion of water into hydrogen and oxygen. The results from these selected studies have allowed greater insight into nanoparticle chemistry and the role of nanoparticles in photochemical conversion of water in to hydrogen and oxygen. Chapter 2 shows that CdSe nanoribbons have photocatalytic activity for hydrogen production from water in the presence of Na2S/Na2SO3 as sacrificial electron donors in both UV and visible light. Quantum confinement of this material leads to an extended bandgap of 2.7 eV and enables the photocatalytic activity of this material. We report on the photocatalytic H2 evolution, and its dependence on platinum co-catalysts, the concentration of the electron donor, and the wavelength of incident radiation. Transient absorption measurements reveal decay of the excited state on multiple timescales, and an increase of lifetimes of trapped electrons due to the sacrificial electron donors. In chapter 3, we explore the catalytic activity of citrate-capped CdSe quantum dots. We show that the process is indeed catalytic for these dots in aqueous 0.1 M Na2S:Na2SO3, but not in pure water. Furthermore, optical spectroscopy was used to report electronic transitions in the dots and electron microscopy was used to obtain morphology of the catalyst. Interestingly, an increasing catalytic rate is noted for undialyzed catalyst. Dynamic light scattering experiments show an increased hydrodynamic radius in the case of undialyzed CdSe dots in donor solution. In chapter 4 we show that CdSe:MoS2 nanoparticle composites with improved catalytic activity can be assembled from CdSe and MoS2 nanoparticle building units. We report on the photocatalytic H2 evolution, quantum efficiency using LED irriadiation, and its dependence on the co-catalyst loading. Furthermore, optical spectroscopy, cyclic voltammetry, and electron microscopy were used to obtain morphology, optical properties, and electronic structure of the catalysts. In chapter 5, illumination with visible light ([lambda]> 400 nm) photoconverts a red V2O5 gel in aqueous methanol solution into a green VO2 gel. The presence of V(4+) in the green VO2 gel is supported by Electron Energy Loss Spectra. High-resolution electron micrographs, powder X-ray diffraction, and selective area electron diffraction (SAED) data show that the crystalline structure of the V2O5 gel is retained upon reduction. After attachment of colloidal Pt nanoparticles, H2 evolution proceeds catalytically on the VO2 gel. The Pt nanoparticles reduce the H2 evolution overpotential. However, the activity of the new photocatalyst remains limited by the VO2 conduction band edge just below the proton reduction potential. Chapter 6 studies the ability of IrO2 to evolve oxygen from aqueous solutions under UV irradiation. We show that visible illumination ([lambda]> 400 nm) of iridium dioxide (IrO2) nanocrystals capped in succinic acid in aqueous sodium persulfate solution leads to catalytic oxygen evolution. While the majority of catalytic hydrogen evolution comes from UV light, the process can still be driven with visible light. Morphology, optical properties, surface photovoltage measurements, and oxygen evolution rates are discussed.

Book excerpt: Two-dimensional (2D) materials for photocatalytic applications have attracted attention in recent years due to their unique thickness-dependent physiochemical properties. 2D materials offer enhanced functionality over traditional three-dimensional (3D) photocatalysts due to modified chemical composition and electronic structures, as well as abundant surface active sites. This book reviews the applications of 2D-related nano-materials in solar-driven catalysis, providing an up-to-date introduction to the design and use of 2D-related photo(electro)catalysts. This includes not only application areas such as fine chemicals synthesis, water splitting, CO2 reduction, and N2 fixation, but also catalyst design and preparation. Some typical 2D and 2D-related materials (such as layered double hydroxides (LDHs), layered metal oxides, transition metal dichalcogenide (TMDs), metal–organic frameworks (MOFs), graphene, g-C3N4, etc.) are classified, and relationships between structure and property are demonstrated, with emphasis on how to improve 2D-related materials performance for practical applications. While the focus of this book will primarily be on experimental studies, computational results will serve as a necessary reference. With chapters written by expert researchers in their fields, Photocatalysis Using 2D Nanomaterials will provide advanced undergraduates, postgraduates and other researchers convenient introductions to these topics.
