Enhancing adsorption-photocatalytic efficiency of BiOBr for Congo red degradation by tuning surface charge and bandgap via Y3+-I− co-doping strategy

Abstract

Metal-ion doping and halogen substitution have been largely applied to tune bandgap of bismuth oxybromide (BiOBr) to upgrade its photodegradation capacity. In the work, the adsorption capacity and photocatalytic behavior...
