Role of titanate-based perovskites in solar water splitting: an overview

Abstract

Abstract Currently, for energy requirement, mainly dependent on fossil fuels which have harmful effects on environment. There is an urgent requirement of alternative energy source. Solar energy is particularly attractive due to cleanliness and inexhaustible nature. The utilization of solar energy is being intensively studied worldwide. Solar water splitting is an encouraging strategy for feasible production of renewable hydrogen. For solar water splitting there is need of non-toxic, low cost, efficient and stable photocatalyst. Recently, titanate-based perovskite photocatalysts have attracted attention for photoelectrochemical water splitting under solar light irradiation. Due to their wide applications, tunable band gap and high photo-corrosion stability titanate-based perovskites are used in hydrogen generation. The main objective of this review is to overview of the recent developments in titanate-based perovskites, their modification and role in hydrogen production under solar light irradiation.
