Sunlight-driven photocatalytic water splitting is one of the most promising approaches to generating renewable hydrogen as an energy source. In recent years, significant progress has been made in the development of photocatalytic water-splitting systems. Among these, the one- and two-step-excitation overall water-splitting processes are most widely investigated. Realization of visible-light-driven overall water splitting is one of the most important goals at present because of the need to obtain systems exhibiting high solar-to-hydrogen energy conversion efficiency for practical applications. The present review focuses on recent progress in the field of photocatalytic water splitting, especially in the research and design of visible-light-driven overall water-splitting systems, and outlines potential strategies to overcome the difficulties related to practical applications.
