Heterogeneous Nanocomposite-Photocatalysis for Water Purification by Rajendra Pawar,Caroline Sunyong Lee Pdf

In Heterogeneous Nanocomposite-Photocatalysis for Water Purification, the authors introduce various heterogeneous photocatalysts based on novel nanostructures of metal oxide semiconductors and graphene used for water purification, including TiO2, Fe2O3, SnO2, WO3 and g-C3N4, and outlines their advantages and drawbacks. The nanocomposite-photocatalysts ZnO and CdS are compared with reduced graphene oxide (rGO), a rapidly growing materials system. The authors describe how the photocatalytic activity of known nanomaterials can be improved by modifying the structural and optical properties (i.e., phase composition). Introductory portion of the book includes a brief survey of all different kinds of heterogeneous photocatalysts Discusses the possible photocatalysis mechanism occurring during the degradation of different toxic pollutants Provides the photoelectrochemical measurement for synthesized catalysts, supporting the effective transportation of photoelectrons resulting into better catalytic properties

Heterostructured Photocatalysts for Solar Energy Conversion by Srabanti Ghosh Pdf

Heterostructured Photocatalysts for Solar Energy Conversion provides a comprehensive description of novel z-scheme hybrid materials based on metal oxide or chalcogenides-based semiconductor, or carbon-based nanomaterials (conducting polymers, graphene, and other carbon materials). The book explores energy conversion applications, such as hydrogen generation, water splitting, CO2 reduction or degradation of organic pollutants, and their associated new material and technology development. The book addresses a variety of topics, such as photochemical processes, materials and fabrication, degradation mechanisms, as well as challenges and strategies. The book includes in-depth discussions ranging from comprehensive understanding, to engineering of materials and applied devices. The concept of visible light active catalysis emerged in recent decades and continues to attract the scientific community. Driven primarily by an opportunity to develop novel multifunctional materials on one hand, and sustainable technologies on the other, several successful approaches have been explored. However, preparation, characterization, and application of visible light active Z-scheme heterojunction-based catalytic nanostructures are still at the foreground of research activity. Provides an overview on recently developed Z-scheme photocatalysts to stress their performance as catalysts Covers most of the important topics in photocatalysis Explores the most recent advances in synthesis to enable deeper understanding of the principles underlying electronic behavior of catalytic nanostructures, mechanistic details, and the evaluation of their effectiveness, as well as perspectives in solar light harvesting Serves as a valuable resource for better understanding of the current state of photocatalysis research and its possible applications in energy domain

Advances in Heterocatalysis by Nanomaterials by Ioannis V. Yentekakis,Wei(Willy) Chu Pdf

Heterogeneous catalysis played, plays, and will continue to play, a major key role in industrial processes for large-scale synthesis of commodity chemicals of global importance, and in catalytic systems that possess a critical role in energy generation and environmental protection approaches. As a result of the ongoing progress in materials science, nanotechnology, and characterizations, great advances have been achieved in heterogeneous catalysis by nanomaterials. Efficient approaches and advanced methods for the design of nano-structured composite materials (up to atomic level), subject to specific nano-morphologies with enhanced metal–metal and metal–support interactions favorable for catalysis (that enable fine-tuning of the critical properties of the designed catalysts), provide optimized catalysts with outstanding performances in numerous eco-friendly and cost-effective applications. Accordingly, great progress has been achieved involving, for example, emissions control, waste treatment, photocatalytic, bio-refinery, CO2 utilization, and fuel cells applications, as well as hydrocarbon processing for H2, added-value chemicals, and liquid fuels production. The themed Special Issue has succeeded in collecting 10 high-quality contributions that cover recent research progress in the field for a variety of applications (e.g., environment, energy, added-value chemicals/organics synthesis, and bio-transformation) declaring the prospect and importance of nanomaterials in all the directions of heterogeneous catalysis.
