Book Synopsis Solar-Energy-Mediated Methane Conversion Over Nanometal and Semiconductor Catalysts by : Hui Song
Download or read book Solar-Energy-Mediated Methane Conversion Over Nanometal and Semiconductor Catalysts written by Hui Song and published by Springer Nature. This book was released on 2020-11-30 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book demonstrates that solar energy, the most abundant and clean renewable energy, can be utilized to drive methane activation and conversion under mild conditions. The book reports that coupling solar energy and thermal energy can significantly enhance methane conversion at mild temperatures using plasmonic nanometal-based catalysts, with a substantial decrease in apparent activation energy of methane conversion. Furthermore, this book, for the first time, reports the direct photocatalytic methane oxidation into liquid oxygenates (methanol and formaldehyde) with only molecular oxygen in pure water at room temperature with high yield and selectivity over nanometals and semiconductors (zinc oxide and titanium dioxide). These findings are a big stride toward methane conversion and inspire researchers to develop strategies for efficient and selective conversion of methane to high-value-added chemicals under mild conditions.
Book Synopsis Inorganic Metal Oxide Nanocrystal Photocatalysts for Solar Fuel Generation from Water by : Troy K. Townsend
Download or read book Inorganic Metal Oxide Nanocrystal Photocatalysts for Solar Fuel Generation from Water written by Troy K. Townsend and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Realizing a method for converting sunlight to renewable fuel may be one of the most important challenges of the century. Water splitting to hydrogen and oxygen gaseous fuels can be powered by the sun using light absorbing catalysts. In the pursuit of cheap, active, and stable catalysts, this dissertation focuses on inorganic metal oxide semiconductor nanocrystals for solar water splitting including their synthesis, characterization and reactivity. The results from this collection of investigations have shed light on the properties of nanomaterials and their light-driven water reduction and oxidation reactions. Chapter 2 shows the effect of cocatalyst deposition onto wide band gap UV-absorbing asymmetric nanoscale niobium oxide crystals. With spatial charge separation in mind, platinum (an electron acceptor and water reducer) and iridium dioxide (a hole scavenger and known water oxidizer) were photodeposited onto H4Nb6O17 crystals to achieve complete water reduction and incomplete water oxidation. In this case, the water oxidation reaction was shown to be confined to a surface-bound peroxide intermediate. Chapter 3 transitions into narrow band gap visible light absorbing Fe2O3 nanocrystal water oxidation catalysts. These materials were synthesized, characterized, visualized with high resolution transmission electron microscopy (HRTEM) and tested for their photocatalytic activity under visible light irradiation while in the presence of aqueous AgNO3, a sacrificial reagent. Chapter 4 describes efforts to advance toward a complete nanoscale water splitting catalyst without reliance on sacrificial reagents. In this case, both half reactions proceed and hydrogen and oxygen are evolved from the solution. Nanoscale SrTiO3 (6.5 nm and 30 nm) was loaded with NiOx and properties were compared with bulk SrTiO3 to elucidate the effects of nanoscaling. Chapter 5 outlines the photogenerated electron/hole pathway in NiOx-STO by specifically loading nickel oxide and/or nickel metal cocatalysts onto bulk SrTiO3 crystals. These materials were tested for water splitting from pure water, and surface photovoltage / electrochemical measurements showed evidence of electron trapping in nickel and hole trapping in nickel oxide, giving rise to a three-component complete water splitter.

Book Synopsis Biomass Conversion by : Chinnappan Baskar
Download or read book Biomass Conversion written by Chinnappan Baskar and published by Springer Science & Business Media. This book was released on 2012-05-08 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: The consumption of petroleum has surged during the 20th century, at least partially because of the rise of the automobile industry. Today, fossil fuels such as coal, oil, and natural gas provide more than three quarters of the world's energy. Unfortunately, the growing demand for fossil fuel resources comes at a time of diminishing reserves of these nonrenewable resources. The worldwide reserves of oil are sufficient to supply energy and chemicals for only about another 40 years, causing widening concerns about rising oil prices. The use of biomass to produce energy is only one form of renewable energy that can be utilized to reduce the impact of energy production and use on the global environment. Biomass can be converted into three main products such as energy, biofuels and fine chemicals using a number of different processes. Today, it is a great challenge for researchers to find new environmentally benign methodology for biomass conversion, which are industrially profitable as well. This book focuses on the conversion of biomass to biofuels, bioenergy and fine chemicals with the interface of biotechnology, microbiology, chemistry and materials science. An international scientific authorship summarizes the state-of-the-art of the current research and gives an outlook on future developments.
Book Synopsis Nanotechnology for Water and Wastewater Treatment by : Piet Lens
Download or read book Nanotechnology for Water and Wastewater Treatment written by Piet Lens and published by IWA Publishing. This book was released on 2013-07-14 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid development of nanoscience enables a technology revolution that will soon impact virtually every facet of the water sector. Yet, there is still too little understanding of what nanoscience and nanotechnology is, what can it do and whether to fear it or not, even among the educated public as well as scientists and engineers from other disciplines. Despite the numerous books and textbooks available on the subject, there is a gap in the literature that bridges the space between the synthesis (conventional and more greener methods) and use (applications in the drinking water production, wastewater treatment and environmental remediation fields) of nanotechnology on the one hand and its potential environmental implications (fate and transport of nanomaterials, toxicity, Life Cycle Assessments) on the other. Nanotechnology for Water and Wastewater Treatment explores these topics with a broad-based multidisciplinary scope and can be used by engineers and scientists outside the field and by students at both undergraduate and post graduate level.
