Abstract

Realizing scalable and cost-effective green hydrogen is indispensable to transitioning towards a sustainable hydrogen-powered economy. In this direction, the photocatalytic overall water splitting (OWS) approach is one of the simplest and most promising methods to generate green hydrogen at scale. Despite the advantages and prospects of the photocatalytic OWS method, the solar-to-hydrogen (STH) conversion efficiency is significantly lower than the electrocatalytic approach. This chapter summarizes the basic principles of OWS, recent developments in various classes of photocatalysts employed, and efforts towards scalable green hydrogen generation with an insight into prospects in OWS to realize 10% STH conversion efficiency.
