Download or read book Photocatalytic Conversion of Methane and Reduction of CO2 with H2O written by Xiang Yu and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photocatalysis is one of the key technologies for clean energy and environmental applications. The number of applications based on photocatalysis has increased dramatically for the past two decades. Photocatalytic activation of C-H bonds is an emerging field. Methane is a promising source of energy with a huge reserve and is considered to be one of the alternatives to non-renewable petroleum resources because it can be converted to valuable hydrocarbon feedstocks and hydrogen through appropriate reactions. However, due to its high stability, high energy is usually consumed for its conversion, which remains a problem to be solved. Methane conversion and reaction mechanism occurring on metal-heteropolyacid-titania nanocomposites were investigated in Chapters 3 and 4. Oxidation of methane has been carried out for more than a century. Since oxygen is a very reactive molecule, methane can react very rapidly with molecular oxygen and is prone to total oxidation till CO2. Therefore, it is difficult to obtain a desired product with high yield and high selectivity. We report here direct and selective photocatalytic highly-selective oxidation of methane to carbon monoxide under ambient conditions. The composite catalysts on the basis of zinc, tungstophosphoric acid and titania exhibit exceptional performance in this reaction, high carbon monoxide selectivity and quantum efficiency of 7.1% at 362 nm. The reaction is consistent with the Mars-Van Krevelen type sequence and involves formation of the surface methoxy-carbonates as intermediates and zinc oxidation-reduction cycling. In the past few decades, extensive research has focused on the direct conversion of methane to alcohols or higher hydrocarbons. The current processes of converting methane to alcohols or olefins are complex and expensive, because they require an intermediate step of reforming methane to syngas. Although the direct conversion of methane to more valuable products has significant environmental and potential commercial value, there is no commercial scale process available. We uncovered highly selective (>90%) quantitative photochemical direct conversion of methane to ethane at ambient temperature over silver-heteropolyacid-titania nanocomposites. The ethane yield from methane reaches 9 % on the optimized materials. High quantum efficiency, high selectivity and significant yield of ethane combined with excellent stability are major advantages of methane quantitative synthesis from methane using the photochemical looping approach. The rise in atmospheric carbon dioxide and the depletion of fossil fuel reserves have raised serious concerns about the subsequent impact of CO2 on the global climate and future energy supply. The use of abundant solar energy to convert carbon dioxide into fuel, such as carbon monoxide, methane or methanol, solves both problems simultaneously and provides a convenient method of energy storage. Chapter 5 addresses a new efficient catalyst for selective CO2 to CO conversion. The zinc containing phosphotungstic acid-titania nanocomposites exhibited exceptional high activity reaching 50 μmol CO/g·h and selectivity (73%) in the CO2 photocatalytic reduction to CO in the presence of water. The in-situ IR experiments suggest that reaction involves zinc bicarbonates containing hydroxyl groups. The decomposition of these zinc bicarbonate species under irradiation leads to the selective production of carbon monoxide and oxygen. In photocatalytic reactions, the difference in catalyst morphology usually has a significant effect on the photocatalytic performance. Chapter 6 studied the effect of monoclinic bismuth vanadate (BiVO4) crystals with controlled ratio of {010} and {110} facets for photocatalytic reduction of CO2 by H2O. The reaction under irradiation is significantly enhanced by selective photo-deposition of Cu and Co co-catalysts over different facets providing Z-scheme charge flow.

This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The increase of the carbon dioxide concentration in the atmosphere provides a strong impetus to discover new catalysts that are able to reduce CO2. The reduction processes of this greenhouse gas CO2 have recently received enormous efforts in the research area. The objective of this thesis was the photocatalytic reduction of CO2 that is known as an artificial photosynthesis using visible light, and the objective of the thesis was to study the ability and efficiency of different new molecular catalysts towards CO2 reduction. The goals of the thesis are to design and characterize new catalysts that have high efficiency for the catalytic reduction of CO2. After a brief introduction in Chapter 1 about the photocatalytic reduction of CO2, a different catalyst is presented in each chapter with their characterization and examination for the photocatalytic reduction of CO2. In addition, these presented catalysts were also examined for the electrocatalytic reduction of CO2, but they show a good catalytic behavior in the photocatalytic reduction of CO2. The catalytic mechanisms were also suggested for each catalyst and tried to be confirmed by many different experiments. observed to be highly influenced by CO2 concentration. These newly discovered catalysts are based on transition metal complexes that are able to be good catalysts for the photocatalytic CO2 reduction. These new transition metal complexes have been synthesized, characterized and examined for their catalytic reactivity for CO2 reduction. As presented in Chapter 2, new manganese and rhenium ccomplexes bearing a phosphino-amino-pyridine ligand were synthesized, characterized and showed their photocatalytic ability for CO2 reduction. In addition, Chapter 3 presents new Ru catalysts supported by an unprecedented ligand array and documented their photocatalytic ability towards CO2 reduction. Moreover, Chapter 4 focuses on new Zn(II) complexes that are novel catalysts in the photocatalytic CO2 reduction area. Furthermore, Chapter 5 presents a new environment for Re photocatalyst that has the switch in product to formic acid compare to all other reported Re photocatalysts. On the other hand, Chapter 6 shows new dimers and monomers for a series of earth-abundant transition metal dibromide complexes supported by a neutral SNS ligand framework and reveals their applications in the catalysis. Finally, Chapter 7 presents a brief conclusion and a number of future directions. The attempts to explore and discover the new catalysts for CO2 reduction were exciting, successfully and resulted in the discovery of new catalysts. These catalysts show their good ability to reduce carbon dioxide (CO2) to more valuable products such as carbon monoxide (CO) and formic acid (HCOOH).

This book was released on 2023-02-09 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work adresses the gap between basic research and applied research in the field of CO₂ electrolysis using molecular catalysts. The development of new catalysts includes important aspects of the industrial application as early as possible to unlock the true potential of a catalyst and to prevent potential problems that occur when changing to industrially relevant process conditions. The results show that unexpected phenomena can occur when scaling up a technology from lab scale to pilot, or even industrial scale, advocating an effort to come as close as possible to large scale conditions, already in the lab. That can prevent major setbacks in the process and save valuable time and effort. This aspect is underlined by recent research in the specific field of CO₂ electrolysis using organometallic complexes, as catalysts show different performance characteristics after immobilization, for example. The successful development of future solutions depends on the interdisciplinary collaboration taking into account molecular considerations as well as process engineering aspects.
