Abstract

Hydrogen is a clean fuel and an efficient energy carrier. Photocatalytic hydrogen production from cheap raw materials like water and industrial waste hydrogen sulfide provides an economical, environmentally friendly solution for future. To ensure efficient conversion of incident solar light photons to charge carriers, appropriate design of a solar photocatalytic reactor is most important. This review focuses on various configurations of photocatalytic reactors used for hydrogen recovery from both water and hydrogen sulfide (both liquid and gas-phase). From the literature review, it was observed that the rate of reaction was much influenced by the reactor configuration adopted. Based on the observations, very few studies were focused for development of solar photo-reactor for the generation of H2. Hence the effective solar photocatalytic generation of H2 from H2S by developing a suitable photo-reactor is essential for large-scale hydrogen recovery.
