TiO2−x/Ag/rGO composites as effective photocatalysts for the degradation of organic pollutants

The incorporation of Ti 3+ and oxygen vacancies in the TiO 2− x NRs/Ag/rGO composites reduces the bandgap of TiO 2 and extends the visible light absorption range due to the SPR effect of Ag NPs and the reduced light reflection in the presence of rGO.
