One-Pot synthesis of Hierarchical CdS/MoS2/rGO with Enhanced (Photo)Electrocatalytic Activities

Abstract A facile one-pot hydrothermal synthesis of 3D windmill-like CdS/MoS2/rGO has been reported. The MoS2/rGO framework prevents the aggregation of CdS and leads to a two-pathway for electron transfer, thus enhancing the electron density and more active site on the rGO surface. Compared with pure CdS, the hierarchical CdS/MoS2/rGO catalyst displays superior photocatalytic H2 production activity and electrocatalytic H2 evolution overpotential, which is 3.5 times in photoactivity and 146.7 mV decrease of overpotential. A new hierarchical structure and its characteristics and mechanism are proposed at the atomic-/nanoscale.
