Book Description
Nanostructured Photocatalysts: From Materials to Applications in Solar Fuels and Environmental Remediation addresses the different properties of nanomaterials-based heterogeneous photocatalysis. Heterogeneous nanostructured photocatalysis represents an interesting and viable technique to address issues of climate change and global energy supply. Sustainable hydrogen (H2) fuel production from water via semiconductor photocatalysis, driven by solar energy, is regarded as a viable and sustainable solution to address increasing energy and environmental issues. Similarly, photocatalytic reduction of CO2 with water for the production of hydrocarbons could also be a viable solution. Sections cover band gap tuning, high surface area, the short diffusion path of carriers, and more. - Introduces the utilization of nanostructured materials in heterogeneous photocatalysis for hydrogen fuel production via water splitting - Explains preparation techniques for different nanomaterials and hybrid nanocomposites, enabling improved sunlight absorption efficiency and enhanced charge separation - Assesses the challenges that need to be addressed before this technology can be practically implemented, particularly of identifying cost-effective nanophotocatalysts

Book Description
This book helps readers comprehend the principles and fundamentals of defect engineering toward realization of an efficient photocatalyst. The volume consists of two parts, each of which addresses a particulate type of defects. The first, larger section provides a comprehensive and rigorous treatment of the behaviour and nature of intrinsic defects. The author describes how their controlled introduction and consequent manipulation over concentration, distribution, nature and diffusion is one of the most effective and practical methodologies to modify the properties and characteristics of target photocatalytic materials. The second part of the book explains the formation of extrinsic defects in the form of metallic and non-metallic dopants and gives a detailed description of their characteristics as this approach is also often used to fabricate an efficient photocatalyst. Filling the gap in knowledge on the correlation between introduction of defects in various semiconducting materials and their photocatalytic performance, the book is ideal for graduate students, academics and researchers interested in photocatalysts, defect engineering, clean energy, hydrogen production, nanoscale advanced functional materials, CO2 deactivation, and semiconductor engineering.

Book Description
Titanium dioxide (TiO2) has drawn considerable attention as an attractive inorganic raw material for various applications due to its inexpensiveness, nontoxic nature, stability, and excellent photocatalytic activity. Photocatalysis is one of the most promising route for sustainable chemistry of the 21st century. It can contribute to solving environmental, global energy, and chemical problems, as well as to the sustainable production of commodities in the near future. This book presents the fundamentals of photocatalysis in nanostructured TiO2 and describes the factors affecting the photocatalytic activity, design, and synthesis of various forms of nanostructured TiO2. It highlights the use of ion-doping and inert-atmosphere annealing to extend the light-absorption range of photocatalysts and reduce recombination between electrons and holes. It discusses numerous applications in the fields of energy and environment, such as water purification, gas sensing, storage and delivery, and energy generation. The book is an invaluable resource and useful guide for a broad readership in various fields of catalysis, materials science, environment, and energy.
