Abstract

A BiVO₄ photoanode was modified with a multi-functional layered double hydroxide (LDH) nanowall overlayer for PEC water oxidation. The composite photoanode exhibits a tremendous cathodic shift of the onset potential (∼540 mV) and more than 2-fold enhancement in the oxidation efficiency and IPCE value.
