The book discusses developing various types of photocatalytic semiconductors and their modification by metallization, sensitization, and doping to enhance photocatalytic activities. It describes the principles and mechanisms of photocatalysis and other possible applications of photocatalysis such as use as antifouling agents, controlling air pollution, self-cleaning of glasses and tiles, green composites, wastewater treatment, hydrogen generation, and inactivation of microorganisms. The book 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.
