Photoelectrocatalysis offers the potential to reduce energy demand and provide different selectivity profiles compared with electrocatalytic analogues, but current systems have shown limited rates. Here, recent advances in light concentration and gas diffusion electrodes are integrated into a photoelectrochemical system for coupled glycerol oxidation and CO2/H2O reduction with photocurrent densities above 100 mA cm−2.
