"Semiconductors are powerful tool for developing new semiconductor-based technologies with environmental applications. This book covers fundamentals about oxides semiconductor, synthesis strategies, their physical properties and applications as catalysts for environmental applications. The purpose of this book is to serve as a base material for students who are starting research in the area of materials focused on environmental applications. Here we offer a broad approach to the topic, as well as we explain in detail the experimental findings published, which is not addressed in other books"-- Provided by publisher.
