Lignin as a quasi-homogenous electron mediator enables efficient photocatalytic H2 evolution in molecular systems

Chem Commun (Camb). 2023 Aug 3;59(63):9607-9610. doi: 10.1039/d3cc02856a.

Abstract

We report that the biomass-derived lignosulfonate (LS) can function as a quasi-homogenous electron mediator to efficiently promote the electron transfer from the excited erythrosin B (ErB) to the in situ generated Pt cocatalyst under visible light, thus enhancing the photocatalytic H2 evolution activity by over 10 fold as compared to the LS-free system.
