Book excerpt: Transition metal nanoparticles and metal oxide have been used extensively for a wide range of applications in electrochemical reactions (HER, ORR, OER) and energy storage (supercapacitors batteries). To make less expensive, the use of transition metal at minimum metal contents without compromising the catalytic activity could be one way. Most of the catalytic process takes place on the¬†surface and reaction dynamic can be manipulated by changing the particle size and shape. For a long time, single metal atom organometallic compounds have been used as a catalyst at the industrial level. However, problems with the homogeneous catalyst to recover back at the end of the process lead to development of heterogeneous single-atom catalysts with equal activity like a homogeneous catalyst. Cobalt single atom has received a tremendous interest of the scientific community due to its excellent catalytic activity and recyclability. Cobalt single-atom catalyst has shown better performance compared with sub-nanometer nanoparticles catalyst for ORR, OER, and HER.¬†This chapter is conferring method of preparation of carbon-based single Co atoms heterogeneous catalyst, their application for ORR, OER, HER reactions, and mechanistic investigations through DFT calculations. The role of single Co metal atoms and anchoring using N or heteroatoms is discussed and compared.

Available in PDF, EPUB and Kindle. Book excerpt: Single Atom Catalysts: Design, Synthesis, Characterization, and Applications in Energy focuses on the synthesis, design and advanced characterization techniques for single atom catalyst materials and their direct energy conversion and storage applications. This book reviews emerging applications of single atom catalysts in fuel cells, batteries, water splitting, carbon dioxide reduction, and nitrogen fixation. Both noble metal and non-noble metal single atom catalysts (SACs) are discussed as noble metal-based SACs are highly efficient and non-noble metal-based SACs might have lower associated costs. There is an emphasis on materials design focused on improving performance of catalysts based on overall catalytic activity, selectivity and stability. Specific parameters that impact this performance are emphasized throughout the book, including single metal atom stabilization, metal-support interactions and the coordination environment. - Discusses the different intricate design and synthesis methods pertaining to various noble and non-noble metal-based SACs - Provides in-depth understanding about the structural, morphological, and physicochemical characterization techniques of synthesized SACs with data analysis and interpretation - Describes state-of-the-art applications of SACs in renewable energy generation and their conversion, storage, and associated challenges

This book was released on 2023-04-07 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Single-atom catalysts (SACs) with high activity, unique selectivity, and nearly 100% atom utilization efficiency are promising for broad applications in many fields. This review aims to provide a summary of the current development of SACs and point out their challenges and opportunities for commercial applications in the energy process. The discussion starts with an introduction of various types of SACs materials, followed by typical SACs synthetic methods with concrete examples and commonly used characterization methods. The state-of-the-art synthesis methods, whereby SACs with stabilized single metal atoms on the substrate without migration and agglomeration could be obtained, are emphasized. Next, we give an overview of different types of substrates and discuss the effects of substrate species on the structure and properties of SACs. Then we highlight the typical applications of SACs and the remaining challenges. Finally, a perspective on the opportunities for the development of SACs for future commercial applications is provided.

Book excerpt: Since the turn of the last century when the field of catalysis was born, iron and cobalt have been key players in numerous catalysis processes. These metals, due to their ability to activate CO and CH, haev a major economic impact worldwide. Several industrial processes and synthetic routes use these metals: biomass-to-liquids (BTL), coal-to-liquids (CTL), natural gas-to-liquids (GTL), water-gas-shift, alcohol synthesis, alcohol steam reforming, polymerization processes, cross-coupling reactions, and photocatalyst activated reactions. A vast number of materials are produced from these processes, including oil, lubricants, waxes, diesel and jet fuels, hydrogen (e.g., fuel cell applications), gasoline, rubbers, plastics, alcohols, pharmaceuticals, agrochemicals, feed-stock chemicals, and other alternative materials. However, given the true complexities of the variables involved in these processes, many key mechanistic issues are still not fully defined or understood. This Special Issue of Catalysis will be a collaborative effort to combine current catalysis research on these metals from experimental and theoretical perspectives on both heterogeneous and homogeneous catalysts. We welcome contributions from the catalysis community on catalyst characterization, kinetics, reaction mechanism, reactor development, theoretical modeling, and surface science.

This book was released on 2013 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chapter 1. Small domains of cobalt on silica (CoSBA) were prepared by the reaction of Co[N(SiMe3)2]2 and SBA-15, resulting in a range of surface structures as the cobalt loading varied from 0.27 to 5.11 wt%. X-ray absorption spectroscopy (XAS) was employed to characterize these surface structures, which range from single-site cobalt atoms to small clusters of Co3O4. The CoSBA materials exhibit photochemical water oxidation catalysis, revealing distinct catalytic activities associated with characteristic types of surface structures that are dominant in particular concentration regimes. The catalytic turnover frequency for water oxidation of an isolated single-site cobalt atom (0.0143 s−1) is much greater than that observed for a surface atom of a small cluster Co3O4 on silica (0.0006 s−1). The CoSBA catalysts were recyclable for more than seven catalytic cycles (> 200 turnovers) with additional sacrificial oxidant, and no leaching of cobalt was observed. Post-catalytic analysis of CoSBA by XAS revealed that the cobalt atoms were partially oxidized to Co3+, without exhibiting significant surface migration and aggregation of cobalt atoms. Chapter 2. Single-site cobalt atoms on various oxide surfaces (TiO2, MgO, SBA-15, AlPO, and Y-Zeolite) were prepared and evaluated as water oxidation catalysts. Superior catalytic rates were observed for cobalt sites on basic supporting oxides (TiO2 and MgO) relative to those on acidic oxides (Y-Zeolite, AlPo, and SiO2). Per-atom turnover frequencies of ca. 0.04 s−1 were achieved, giving initial rates 100 times greater than a surface atom of a Co3O4 nanoparticle. No correlation was observed between catalytic rates and oxygen atom affinities of the supporting oxides. Chapter 3. Cobalt metaphosphate Co(PO3)2 nanoparticles are prepared via the thermolytic molecular precursor (TMP) method. A Ni foam electrode decorated with Co(PO3)2 nanoparticles is evaluated as an anode for water oxidation electrocatalysis in pH 6.4 phosphate-buffered water. Catalytic onset occurs at an overpotential of ca. 310 mV, which is 100 mV lower than that observed for Co3O4 nanoparticles, with a comparable surface area under identical conditions. A per-metal turnover frequency (TOF) of 0.10 - 0.21 s−1 is observed at [eta] = 440 mV, which is comparable to the highest rate reported for a first-row metal heterogeneous catalyst. Post-catalytic characterization of the catalyst resting state by XPS and Raman spectroscopy reveals that surface rearrangement occurs, resulting in an oxide-like surface overlayer. Chapter 4. Linear trimetallic CoIII/CoII/CoIII cobalt complexes with bridging acyl-alkoxy ligands are electrocatalysts for the reduction of tosic acid in acetonitrile. The -OCMe2CH2COMe complex appears to operate homogeneously, and at an onset overpotential of only 25 mV. A turnover frequency of ca. 80 s−1 was observed at an overptotential of 150 mV.
