A Review on Harnessing Photocatalysis for Dual Benefits: Hydrogen Production and Biomass Conversion

Abstract Global energy consumption is increasing rapidly; while primary energy resources are diminishing with time. Further, extensive usage of fossil fuel‐based resources results in unfavorable consequences such as pollution and climate change. As a result, global attention is drawn to the sustainable generation of clean fuel from renewable energy. In this context, hydrogen (H 2 ) is gaining tremendous interest researchers as a clean, environmentally benign alternative to fossil fuels that can be used directly in automobiles or in fuel cells to generate power. Biomass, on the other hand, is one of the most abundant carbon‐based renewable energy sources as plants create it through photosynthesis. Consequently, controlled degradation of raw biomass can produce ethanol, furans, 5‐hydroxymethylfurfural, lactic acid, succinic acid, and other key intermediates which can be further converted into value‐added compounds. In light of these advantages, recent studies show that photocatalytic H 2 production from water can be coupled with the valorization of biomass derivatives to develop a greener and environmentally friendly protocol to produce value‐added chemicals. Herein, a comprehensive account of the recent developments in the area of visible light‐assisted simultaneous production of H 2 and value‐added chemicals from biomass derivatives is provided.
