Chapter 8 - Recent advances in sacrificial reagents toward sustainable light-driven photocatalytic hydrogen evolution

Abstract

This chapter presents a review of the status of research focusing on the light-driven photocatalytic hydrogen (H2) evolution, with main focus on using sacrificial reagents. First, the basic light-driven catalytic through water splitting, including one-step and Z-scheme reactions, is addressed. There remain challenges, including low catalytic activity, poor stability, etc. Following it, a summary of using sacrificial reagents for photocatalytic H2 generation is collected and discussed. This perception performs higher rates and better stability than that of true water splitting. It notes that the research on the sustainable generation of H2 through photocatalysis is still in an early stage. Therefore considerable efforts on photocatalysts are required to make this concept highly efficient, ecologically friendly, technologically reliable, and relatively low-cost feasible.
