The use of photoelectrochemical (PEC) water splitting to harvest intermittent solar sources in the form of hydrogen is an attractive potential method to address energy and environmental issues. Since 1972, when Honda and Fujishima demonstrated the use of titanium dioxide (TiO2) in PEC water splitting (1), extensive efforts have been devoted to the development of photoelectrode stability and high solar-to-hydrogen efficiency. Metal oxides (e.g. TiO2, Fe2O3, BiVO4, and SrTiO2) have been extensively studied but their large band gap and sluggish charge transfer kinetics typically limited their solar-to-hydrogen conversion efficiency (1-9). III-V semiconductor materials have proven attractive for PEC water splitting due to their high efficiency, optimal band gap, and excellent optical properties but they are readily susceptible to corrosion in strongly acidic or basic aqueous solutions during the PEC process (10-18). This thesis aims to construct a PEC device (e.g. photoanode and photocathode) based on III-V semiconductor materials (such as InGaN, GaP, and GaPSb) for PEC water splitting. The design of a direct PEC water splitting device requires a suitable band gap to cover the entire solar spectrum (visible range), which leads to a high photocurrent and solar-to-hydrogen (STH) efficiency. The band edge alignment must straddle the hydrogen and oxygen redox potentials and stable under illumination in electrolyte conditions (19). However, the current challenge is to develop efficient and stable solar-to-chemical conversion systems based on III-V semiconductor materials for PEC water splitting. This can be addressed by incorporating novel co-catalysts that are physically and electrically attached to the surface of the photoelectrodes. The role of the co-catalyst is to minimize the overpotentials and accelerate the charge kinetics at the semiconductor/electrolyte interface (20). Additionally, the surface modification strategy of applying co-catalysts can extend the stability of the photoelectrode for long-time operation (21-25).
There has been a resurgence of interest in light-induced water splitting as the search for storable carbon neutral energy becomes more urgent. Although the history of the basic idea dates back more than four decades, efficient, economical and stable integrated devices have yet to be realized. In the continuing quest for such devices, the field of photoelectrochemistry is entering a new phase where the extraordinary interdisciplinary of the research and development efforts are opening new avenues. This aspect of current research effort is reflected in the chapters of this book, which encompass present thinking in the various disciplines such as materials science, photo-electrochemistry and interfaces that can contribute to realization of viable solar fuel generators. This book presents a blend of the background science and recent advances in the field of photoelectrochemical water splitting, and includes aspects that point towards medium to long term future realization. The content of the book goes beyond the more traditional approaches to the subject by including topics such as novel excitation energy processes that have only been realized so far in advanced photonics. The comprehensive overview of current activities and development horizons provided by the impressive collection of internationally renowned authors therefore represents a unique reflection of current thinking regarding water splitting by light.

This book outlines many of the techniques involved in materials development and characterization for photoelectrochemical (PEC) – for example, proper metrics for describing material performance, how to assemble testing cells and prepare materials for assessment of their properties, and how to perform the experimental measurements needed to achieve reliable results towards better scientific understanding. For each technique, proper procedure, benefits, limitations, and data interpretation are discussed. Consolidating this information in a short, accessible, and easy to read reference guide will allow researchers to more rapidly immerse themselves into PEC research and also better compare their results against those of other researchers to better advance materials development. This book serves as a “how-to” guide for researchers engaged in or interested in engaging in the field of photoelectrochemical (PEC) water splitting. PEC water splitting is a rapidly growing field of research in which the goal is to develop materials which can absorb the energy from sunlight to drive electrochemical hydrogen production from the splitting of water. The substantial complexity in the scientific understanding and experimental protocols needed to sufficiently pursue accurate and reliable materials development means that a large need exists to consolidate and standardize the most common methods utilized by researchers in this field.
Cleavage of water to its constituents (i.e., hydrogen and oxygen) for production of hydrogen energy at an industrial scale is one of the "holy grails" of materials science. That can be done by utilizing the renewable energy resource i.e. sunlight and photocatalytic material. The sunlight and water are abundant and free of cost available at this planet. But the development of a stable, efficient and cost-effective photocatalytic material to split water is still a great challenge. To develop the effective materials for photocatalytic water splitting, various type of materials with different sizes and structures from nano to giant have been explored that includes metal oxides, metal chalcogenides, carbides, nitrides, phosphides, and so on. Fundamental concepts and state of art materials for the water splitting are also discussed to understand the phenomenon/mechanism behind the photoelectrochemical water splitting. This book gives a comprehensive overview and description of the manufacturing of photocatalytic materials and devices for water splitting by controlling the chemical composition, particle size, morphology, orientation and aspect ratios of the materials. The real technological breakthroughs in the development of the photoactive materials with considerable efficiency, are well conversed to bring out the practical aspects of the technique and its commercialization.
