A novel visible-light-driven Cu/rGO/MoS₂ (CRM) ternary nanostructure as a photocatalyst with high catalytic activity towards environmental purification using solar energy was successfully synthesized through a facile solvothermal method. It was found that the nanoflower structure of MoS₂ increased the number of its exposed edges. Meanwhile rGO as a catalytic substrate played a role of charge-carrier channel to improve the separation of holes and electrons, which originated from the band gap absorption of MoS₂. The content of Cu in photocatalyst affected photocatalytic performance obviously. And the optimal 30% Cu/rGO/MoS₂ possessed the highest photocatalytic performance, which could be attributed to the improved separation of charges and synergistic effects among Cu, rGO and MoS₂. The removal efficiency of Rhodamine B (RhB) over CRM was up to 100% in 5 min. CRM as a photocatalyst maintained good reproducibility and stability during 3 times of the recycle experiments. These results indicate CRM is a promising photocatalyst for degrading organic pollutants in wastewater.
