Discussion on Solar Photocatalytic Degradation of Treated Leachate Using Transition Metal-Nonmetal Co-Doped TiO₂

Abstract:

Leachate biochemical effluent containing large quantities of refractory matters are difficult to degrade by traditional biological processes. Photocatalysis technology seems to be a promising solution for leachate biochemical effluent because it can oxidize refractory organic compounds to harmless inorganics. But there are two key problems in TiO₂ photocatalytic degradation of biologically treated leachate. One is low quantum yield, the other is low photocatalytic activity in the visible-light region. The advice about solar photocatalytic degradation of biologically treated leachate using transition metal-nonmetal co-doped TiO₂ is put forward.
