The photoelectrochemical (PEC) water splitting efficiency of a photoanode is restricted by charge recombination and sluggish reaction kinetics. Here, we demonstrated the spatial engineering of an ultrathin Co(OH)ₓ encapsulated p-Cu₂S/n-BiVO₄ photoanode for simultaneously enhancing charge separation...
