Photocatalysis reactions carried out in the presence of a semiconductor and light is rapidly becoming one of the most active areas of chemical research with applications in areas such as electrochemistry medicine and environmental chemistry Photocatalysis: Principles and Applications stresses the development of various types of photocatalytic semiconductors including binary ternary quaternary and composite and their modifications by metallization sensitization and doping to enhance their photocatalytic activities. In addition to describing the principles and mechanisms of photocatalysis it also discusses other possible applications of photocatalysis such as use as antifouling agents controlling air pollution by degrading contaminants present in the environment self-cleaning of glasses and tiles in the presence of light/artificial light green composites wastewater treatment hydrogen generation and inactivation of microorganisms. The book also describes medical applications and summarizes efforts in the field of photosplitting of water as a newer energy source and photoreduction of carbon dioxide for providing synthetic fuels and also a step towards mimicking photosynthesis. Introduces the basic principle of photocatalysis. Provides an overview of the types of semiconductors their immobilization and modifications to make them more active. Gives possible applications of photocatalysis in wastewater treatment and strategy to combat against different kinds of pollutions like water air and soil. Summarizes efforts in the field of photosplitting of water as a newer energy source and photoreduction of carbon dioxide for providing synthetic fuels and as a step towards mimicking photosynthesis.
