| Abstract: |
| The surface plasmon resonance photocatalyst of Ag-AgBr /Al2O3 was synthesized by chemical precipitation and photochemical reduction method.AgBr nanoparticles were loaded onto the mesoporous aluminium oxide carrier by a precipitation reaction，and some of the AgBr particles were reduced to Ag particles under halogen tungsten lamp irradiation.The samples obtained were characterized by SEM，TEM，XRD and UV-Vis spectroscopy.The photocatalytic properties of catalyst were studied with methylene blue pollutant degraded under a visible light source.The results showed that the degradation rate of 5 mg/L methylene blue reached more than 95% and the removal rate of TOC was 70% under 60 min visible light irradiation.The catalyst showed highly efficient and stable under visible light illumination，and could be applied expansively in the field of developing new pattern visible light plasmon induced photocatalysts. |
