Photocatalytic oxidation is effective degradation technology of organic contaminants for wastewater treatment, and it reveals many advantages including high processing efficiency, simple process equipment, easy operating conditions and so on. Nevertheless, for current industrial photocatalytic materials, ultraviolet can only be utilized for catalytic reactions, resulting in very low light energy utilization rate. Mo S2 with a narrow band gap is an ideal visible-light-induced photocatalyst to utilize solar e...
