Abstract

Ultrathin ZnIn₂S₄ nanosheets (NSs) are grown on Co/N-doped graphitic carbon (NGC) nanocages, composed of Co nanoparticles surrounded by few-layered NGC, to obtain hierarchical Co/NGC@ZnIn₂S₄ hollow heterostructures for photocatalytic H₂ generation with visible light. The photoredox functions of discrete Co, conductive NGC, and ZnIn₂S₄ NSs are precisely combined into hierarchical composite cages possessing strongly hybridized shell and ultrathin layered substructures. Such structural and compositional virtues can expedite charge separation and mobility, offer large surface area and abundant reactive sites for water photosplitting. The Co/NGC@ZnIn₂S₄ photocatalyst exhibits outstanding H₂ evolution activity (e.g., 11270 µmol h⁻¹ g⁻¹) and high stability without engaging any cocatalyst. © 2019 WILEY-VCH Verlag GmbH & Co.
