Three-dimensional MoS2–CdS–γ-TaON hollow composites for enhanced visible-light-driven hydrogen evolution

Abstract

Three-dimensional MoS₂–CdS–γ-TaON hollow composites have been successfully synthesized by anchoring MoS₂–CdS nanocrystals on the surfaces of γ-TaON hollow spheres via a two-step ion-exchange route with assistance from a hydrothermal process. Even without the noble-metal cocatalyst, the as-prepared MoS₂–CdS–γ-TaON hollow structure with 1 wt% MoS₂/CdS cocatalyst (0.2 wt% MoS₂) decorated on its surface produces a high photocatalytic hydrogen production rate of 628.5 μmol h⁻¹.
