Reaction mechanism and metal ion transformation in photocatalytic ozonation of phenol and oxalic acid with Ag＋/TiO2

Photocatalytic ozonation of phenol and oxalic acid （OA） was conducted with a Ag^＋/TiO2 catalyst and different pathways were found for the degradation of different compounds. Ag^＋ greatly promoted the photocatalytic degradation of contaminants due to its role as an electron scavenger. It also acceler...
