Book Description
The research presented here is focused on design, synthesis, and characterization of transition metal oxides for catalytic and energy applications. The first part is devoted to discuss catalytic applications of mesoporous manganese oxides and the second part is devoted to discuss novel solvent driven synthesis of sodium tungsten bronze nanomaterials for energy applications. From the standpoint of green chemistry, the investigation of simple, low cost, stable, environmentally friendly, and potentially active materials for complete oxidation reactions at low temperatures is highly desirable. In recent years, green chemical approaches have become an integrated part of daily life and implementation of this modern discipline led to momentous ecological benefits, innovations and a strengthened economy. My research is devoted to investigate potential materials in oxidative catalysts that resonate with the concepts in green chemistry. The first part of this thesis will discuss the importance of catalytic oxidation reactions, synthesis, and characterization of the mesoporous manganese oxide materials and their applications in a series of complete oxidation reactions. The projected decline in fossil fuels and growing global energy consumption demands alternatives for petroleum feedstock and sustainable conversion processes for energy production. Thus, applicability of mesoporous manganese oxides on complete catalytic oxidation of methane has been discussed. Secondly, complete catalytic oxidation of diesel particulate matter (DPM) which is an unsolicited byproduct emitted by diesel exhaust engines is discussed. In the second part of this thesis, design of novel, solvent driven in situ synthesis method of sodium tungsten bronze is discussed. Tungsten bronzes are well defined, unique class of non-stoichiometric compounds with exclusive characteristic properties. They have attracted much attention in the past few decades due to their wide variety of crystal structures and interesting electro-optic, photochromic, and super-conducting properties However, the synthesis of cubic sodium tungsten bronze nanomaterials with high conductivity is not much reported due to the limitations of high temperature synthetic approaches.

Book Description
Exhibiting both homogeneous and heterogeneous catalytic properties, nanocatalysts allow for rapid and selective chemical transformations, with the benefits of excellent product yield and ease of catalyst separation and recovery. This book reviews the catalytic performance and the synthesis and characterization of nanocatalysts, examining the current state of the art and pointing the way towards new avenues of research. Moreover, the authors discuss new and emerging applications of nanocatalysts and nanocatalysis, from pharmaceuticals to fine chemicals to renewable energy to biotransformations. Nanocatalysis features contributions from leading research groups around the world. These contributions reflect a thorough review of the current literature as well as the authors’ first-hand experience designing and synthesizing nanocatalysts and developing new applications for them. The book’s nineteen chapters offer a broad perspective, covering: Nanocatalysis for carbon-carbon and carbon-heteroatom coupling reactions Nanocatalysis for various organic transformations in fine chemical synthesis Nanocatalysis for oxidation, hydrogenation, and other related reactions Nanomaterial-based photocatalysis and biocatalysis Nanocatalysts to produce non-conventional energy such as hydrogen and biofuels Nanocatalysts and nano-biocatalysts in the chemical industry Readers will also learn about the latest spectroscopic and microscopy tools used in advanced characterization methods that shed new light on nanocatalysts and nanocatalysis. Moreover, the authors offer expert advice to help readers develop strategies to improve catalytic performance. Summarizing and reviewing all the most important advances in nanocatalysis over the last two decades, this book explains the many advantages of nanocatalysts over conventional homogeneous and heterogeneous catalysts, providing the information and guidance needed for designing green, sustainable catalytic processes.

Book Description
This volume continues the tradition formed in Nanotechnology in Catalysis 1 and 2. As with those books, this one is based upon an ACS symposium. Some of the most illustrious names in heterogeneous catalysis are among the contributors. The book covers: Design, synthesis, and control of catalysts at nanoscale; understanding of catalytic reaction at nanometer scale; characterization of nanomaterials as catalysts; nanoparticle metal or metal oxides catalysts; nanomaterials as catalyst supports; new catalytic applications of nanomaterials.

Book Description
This book guides beginners in the areas of thin film preparation, characterization, and device making, while providing insight into these areas for experts. As chemically deposited metal oxides are currently gaining attention in development of devices such as solar cells, supercapacitors, batteries, sensors, etc., the book illustrates how the chemical deposition route is emerging as a relatively inexpensive, simple, and convenient solution for large area deposition. The advancement in the nanostructured materials for the development of devices is fully discussed.

Book Description
This timely publication bridges and presents the latest trends and updates in three hot topics of current and future society: nanomaterials, energy and environment. It provides the state-of-the-art as well as current challenges and advances in the sustainable preparation of metal nanoparticles and their applications. The book fills a critical gap in a multidisciplinary area of high economic, social and environmental importance. Currently, there are no books published that deal with these ever increasing important topics, as most books in this area focus on a particular topic (eg. nanomaterials or catalysis or energy or environment). This is the first multidisciplinary edited book covering the very basics to the more advanced, trendy developments, containing a unique blend of nano, green, renewable and bio.
