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

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