Abstract

The most promising sustainable alternative renewable fuel deemed by the majority to be Hydrogen. Water splitting is the mainly amiable approach for the production of green energy (hydrogen) to address the world energy crisis on both fuel and environment, thereby cogent argument is needed for the actualization of hydrogen economy. Consequently, the improvement of non-hazardous, economical and high-efficiency photocatalysts is vital. Titanate perovskites are a class of compound with general formula ATiO₃ (where A= Ca, Co, Cd, Fe, Ni, Pb, and Sr). Rigorous consideration involved by active titanate perovskites, been photoactive materials; widely known photo-corrosion stability and optically tunable. Though, the solar-to-hydrogen (STH) renovation effectiveness of perovskite materials is at a standstill, due to high rate of photogenerated electron-hole pair recombination and poor photocatalytic presentation. This review provides an overview on the brief discussion of diverse visible light active modified titanate perovskites and their respective structures as reported. The purpose of this review is to describe recent results and developments in visible light active titanate perovskites, as well as to deliver some beneficial suggestions for future research over highly effectual perovskite-based photocatalysts for hydrogen fuel generation.
