Photochemical Splitting of Water: Fundamentals to Applications brings together information on photochemical water splitting for hydrogen production, covering basic concepts, mechanisms, instrumentation, experimental set-up, analysis, materials used as catalysts, innovative methods, and future opportunities. The book introduces the role of water splitting and hydrogen production in the current and future global energy mix and provides a basic understanding of the theories behind photochemical water splitting, instrumentation, experimental set-up, and the criteria for materials selection. Other sections offers thorough coverage of the use of specific cutting-edge active materials in photocatalytic and photoelectrocatalytic water splitting processes, discussing recent advances and future opportunities. The final chapters of the book focus on challenges, emerging trends, and key opportunities for the future, including tandem approaches that combine a solar cell with a suitably formulated water splitting cell. A glossary of technical terms is also included, providing a clear explanation of the main concepts.
