Noble Materials for Photoelectrochemical Water Splitting

Bijoy Tudu, Rajashree Bortamuly, Pranjal Saikia

Development of stable and highly efficient photoelectrodes capable of harvesting solar energy is an essential need of the hour to deal with the global energy demand. Photoelectrochemical (PEC) water splitting is a clean methodology utilizing solar light to produce clean and sustainable hydrogen energy. The best approach to achieve high solar-to-hydrogen energy conversion efficiency is the design of efficient noble materials capable of plasmonic absorption, competent charge separation and their utilization. This chapter presents the recent development on noble metals based photocatalysts that have been widely applied in PEC water splitting.
