Synergistic effect of reduced graphene oxide and near-infrared light on MoS2-mediated electrocatalytic hydrogen evolution

This work presents an effective way of enhancing MoS2-mediated electrocatalytic hydrogen evolution, by exploiting the synergistic effect of reduced graphene oxide (rGO) and near-infrared (NIR) light. Various rGO-MoS2 composites were obtained via hydrothermal method. The optimized composite, 0.2rGO-MoS2 exhibited enhanced electrocatalytic hydrogen evolution activity in a wide pH range under NIR irradiation, without adding noble metal. The...
