Hierarchical Cu₂S Microsponges Constructed from Nanosheets for Efficient Photocatalysis

3D porous hierarchical Cu2S microsponges (HCMs) constructed from 2D ultrathin active nanosheets (∼1.5 nm) with nearly 99% exposed (111) facets are fabricated by a simple hydrothermal route. The as-prepared HCMs possess an improved visible-light-harvesting ability, high surface area, low electron–hole recombination, and excellent photocatalytic activity for phenol degradation under visible light irradiation.
