以石墨烯为载体,通过化学沉积与光还原法制备了具有等离子体共振效应的Ag-AgBr/RGO可见光催化剂。采用XRD 及 UV-Vis 吸收光谱对催化剂进行结构与性能表征,并考察其降解甲基橙溶液的光催化性能。研究结果表明,在可见光下照射60min,催化剂对10 mg·L-1甲基橙溶液的降解率达91%。由于表面金属的等离子体共振效应和石墨烯的协同作用,石墨烯为载体的催化剂的可见光催化活性比氧化铝为载体时高。

The surface plasmon resonance photocatalyst of Ag-AgBr/RGO was synthesized by chemical precipitation and photochem-ical reduction method. The samples were characterized by XRD and UV-Vis spectroscopy. The photocatalytic properties of catalyst were studied with helianthine pollutant degraded under a visible light source. The results showed that the degradation rate of 10 mg ·L-1 helianthine reached more than 91%under 60 min visible light irradiation. Because of synergies between plasmon resonance effect of nano-siliver and the RGO,the catalysts have high activity.
