Abstract Hydrogen generation by solar-driven water splitting is considered as a promising strategy to address energy crisis and environmental emission issues. Bismuth vanadate (BiVO4) is a highly promising photoanode material for photoelectrochemical (PEC) water splitting, but its severe bulk and surface charge recombination, sluggish oxygen evolution reaction (OER) kinetics and narrow visible light harvesting are still bottlenecks. Here, an excellent CQDs/FeOOH/BiVO4 photoanode was designed by co-modification of carbon quantum dots (CQDs) and ultrathin β-FeOOH layers (
