Abstract

A photonic crystal-based CdS–Au–WO₃ heterostructure was constructed on WO₃ photonic crystal segments. Highly efficient visible-light-driven hydrogen and oxygen evolution are demonstrated relative to those of single-, two-component and unstructured systems due to good light harvesting of photonic crystals and efficient electron transfer of this heterostructure.
