Preparation of a Coal-Based MoS/SiO/GO Composite Catalyst and Its Performance in the Photocatalytic Degradation of Wastewater and Hydrogen Production.

Photocatalytic degradation of wastewater and the simultaneous production of hydrogen (H) is a green and efficient method to solve energy and environmental problems. In this paper, coal-based SiO/GO with a stable structure was prepared by a modified Hummers oxidation method, and then, a lotus-shaped composite photocatalyst, MoS/SiO/GO, was prepared by in situ loading of flower cluster MoS from sodium molybdate reduction onto SiO/GO. Its photocatalytic degradation of wastewater and H production properties were investigated while characterizing the material structure.
