摘要：
Three-dimensional MoS2-CdS-gamma-TaON hollow composites have been successfully synthesized by anchoring MoS2-CdS nanocrystals on the surfaces of gamma-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-gamma-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 mu mol h(-1).
