Using AgNO3 as the Ag source, the [email protected] photocatalyst was prepared by depositing noble metal Ag on the surface of BiOCl by solvothermal method. Ag exists as spherical particles with a diameter of 40 nm. Based on the surface plasmon resonance effect (SPR) of Ag, the photoresponse range of BiOCl was successfully extended to the visible light region, which reduced the photo-generated electron-hole recombination efficiency and improved the charge transfer efficiency. The photocatalytic performance of [email protected] was studied under visible light. The results show that when the Ag content is 10wt%, it exhibits excellent effects on the degradation of acid red B (ARB), and its degradation rate constant is 11 times larger than that of BiOCl. The active substance-capturing test results show that the main role in photocatalytic degradation of ARB is voids.
