A Review on Photocatalytic Water Splitting

Abstract

Light driven water splitting associated with hydrogen production is a promising technology and an ideal pro cess in order to furnish high yield of energy via renewable and clean energy sources as well as to lessen the consequences of global warming. In this review paper, thermodynamics for selective photocatalytic generation of hydrogen is focussed on. In fact, recent progress in photocatalysts, manufacture of innovative heterojunction establishments and factors exerting a profound influence on photocatalytic activity for dynamic preparation of H2 have been thrown light upon. The strategies to ameliorate various factors regarding photocatalytic splitting of water such as Z-scheme arrangements as well as impact of operating parameters like band gap, temperature, intensity of light, morphology, pH and sacrificial reagents have been discussed. Computational studies have provided new methods of approach so as to comprehend and anticipate the density of electrons of excited states and band structure of novel synthesized substances. It has the capability to lead to a pathway for cogent outline for effective photo catalysts required for splitting of water. The upcoming scope of research and prospective benefits of this field are also considered herein.
