Functionalized Nanomaterials for Catalytic Application

The term 'green chemistry' was coined by Anastas and Warner in the early 1990s and it is nowadays the mainstay of designing and implementing advanced chemical processes that decrease or eliminate the use and generation of hazardous substances whilst minimizing energy consumption.Solution Combustion Synthesis of Nanostructured Solid Catalysts for Sustainable Chemistry is an interdisciplinary collection of fundamental and applied cutting-edge studies which highlight general and specific aspects of the synthesis of nanostructured catalysts through Solution Combustion Synthesis (SCS), studying their applications from the perspective of green chemistry.This book intends to integrate the fundamental principles of the SCS process with its engineering aspects and covers the synthesis of a wide variety of catalytic materials. This reference book can be used as a permanent consulting material for students, researchers and the general readership for green chemistry, nanochemistry, materials science and chemical engineering.

Heterogeneous catalysts are an important tool for greener catalytic processes due to the ease of their removal from the reaction mixture and feasibility of reuse. When these catalysts can operate in the ideal green solvent, water, they improve the sustainability of the process. This book explores aqueous mediated heterogeneous catalysts and their use in synthesis. Topics covered include nanomaterials, quantum dots, metal organic frameworks, and their use as catalysts.

Silicon-Based Hybrid Nanoparticles: Fundamentals, Properties, and Applications focuses on the fundamental principles and promising applications of silicon-based hybrid nanoparticles in nanoelectronics, energy storage/conversion, catalysis, sensors, biomedicine, environment and imaging. This book is an important reference source for materials scientists and engineers who are seeking to understand more about the major properties and applications of silicon-based hybrid nanoparticles. As the hybridization of silicon nanoparticles with other semiconductors or metal oxides nanoparticles may exhibit superior features, when compared to lone, individual nanoparticles, this book provides the latest insights. In addition, the silicon/iron oxide hybrid nanoparticles also possess excellent fluorescence, super-paramagnetism, and biocompatibility that can be effectively used for the diagnostic imaging system in vivo. Similarly, gold-silicon nanohybrids could be used as highly efficient near-infrared hyperthermia agents for cancer cell destruction. Outlines the major thermal, electrical, optical, magnetic and toxic properties of silicon-based hybrid nanoparticles Describes major applications in energy, environmental science and catalysis Assesses the major challenges to manufacturing silicon-based nanostructured materials on an industrial scale

First-generation ethanol plants did not have many operational challenges as the feedstocks (e.g., corn) used for fuel production are dense, stable, storable, and shippable commodity-type products with fewer conversion challenges. These feedstock properties led the first-generation large-scale biorefineries to grow exponentially. In the second-generation biofuels, the feedstocks used are agricultural and forest residues, dedicated energy crops, industrial wastes, and municipal solid waste. When the industry tested these feedstocks for biofuel production, they faced flowability, storage, transportation, and conversion issues. One way to overcome some of the feeding, handling, transportation, and variable moisture challenges is to densify the biomass. Pellet mills and briquette presses are commonly used to produce densified products. The densified products have uniform size, shape, higher bulk density, and better downstream conversion performance. Also, the densified products are aerobically stable and can be stored for longer durations without any loss in quality.This book's focus is on understanding how the densification process variables, biomass types and their blends, mechanical preprocessing, and thermal and chemical pretreatment methods impact the quality of the densified products produced for biofuel production. Finally, the book also explores the conversion performance of densified biomass for biofuel production.
