Effect of nitridation on visible light photocatalytic behavior of microporous (Ag, Ag2O) co-loaded TiO2

Solvothermal approach followed by calcination is used to obtain Ag and Ag2O co-loaded TiO2 microspheres (Ag-Ag2O-TiO2) with high specific surface area (43.8 m2g-1) and good photocatalytic performance. Interestingly nitridation of (Ag, Ag2O) co-loaded TiO2 deleteriously impacts photocatalytic performance; this is due to (a) reduction of Ag2O to Ag and (b) Ag agglomeration and grain growth.270
