Photoelectrochemical hydrogen evolution from biomass conversion using perovskite solar cells

Abstract

Lignocellulosic biomass presents a renewable alternative to fossil carbon sources for the production of commodity chemicals and fuels. Photoelectrochemical biomass conversion produces carbon-free fuel in the form of molecular hydrogen and simultaneously provides a source of value-added chemical products. Recently in Nature Communication , S.Y. Jang, J.-W. Jang, J. Ryu, and co-workers reported bias-free photoelectrochemical solar hydrogen production coupled to lignocellulosic biomass degradation using a perovskite-based photocathode with anodic lignin depolymerization mediated by phosphomolybdic acid.
