Enhanced photocatalytic performance of Ag-BiOBr nanosheets under LED with different wavelengths.

ABSTRACT: The surface deposition of noble metals can effectively improve photocatalytic performance by the effect of electron trapping (ET) or surface plasmon resonance (SPR), but it is not clear which effect dominates the photocatalytic degradation of organic dyes under light irradiation at specific wavelengths. In this work, a series of xAg-(1-x)BiOBr (x = 0.01, 0.02, 0.03, 0.04, 0.05, and 0.06) nanosheets were synthesized via an ultrasonic-assisted chemical coprecipitation and photo-deposition reaction. The effect of light-emitting diode (LED) with different wavelengths on the photocatalytic degradation of Rhodamine B (RhB) dye was investigated. The results revealed that the hole (h⁺) and superoxide free radical (O₂˙^-) of xAg-(1-
