Photocatalytic degradation of xanthate in flotation plant tailings by TiO2/graphene nanocomposites

Man Jiang et al.

Summary: This study successfully prepared a TiO2/graphene (TiO2/G) composite photocatalytic material via the hydrothermal method. The TiO2/G nanocomposites showed a large specific surface area, small pore size, and low electron-hole pair complexation rate, resulting in efficient degradation of pollutants. By anchoring TiO2 on graphene oxide (GO), the photoresponse range of TiO2/G was broadened and its photocatalytic efficiency was significantly improved. This work is important for the development of photocatalytic systems for the treatment of mineral processing wastewater.
