文摘

Novel RGO/Ag2S/TiO2 UV-NIR response heterostructure photocatalysts have been synthesized successfully. Strong absorption of UV-NIR light improves the sunlight utilization effectively and the degradation rate of organic pollutants. The synergetic effects of RGO, Ag2S and TiO2 enhance the photocatalytic activity and stability.
