双金属二氧化钛复合材料的制备及其在水处理中的应用
Preparation of Bimetallic Titanium Dioxide Composite and its Application in Water Treatment
摘要
Abstract
Objective] To prepare the bimetallic Au-Cu nanoparticle modified TiO2, and to enhance photocatalytic activity of TiO2.[Meth-od] Radiolysis was used to synthesize Au-Cu NPs colloid, which were deposited on the surface of TiO2 .The prepared Au-Cu-TiO2 composite was characterized by TEM, UV-Vis, DSR, the photocatalytic performance of which was evaluated by degrading the target pollutants rhodan-mine B and phenol under UV or visible light.[Result] The TiO2 loading NPs had the smallest mean size of 3.8 nm when the ratio of Au/Cu was 1∶3, and the composite had the highest activity.[Conclusion] The bimetallic Au-Cu NPs had higher efficiency than that of Au in photo induced electron trapping, causing the enhancement of photocatalytic activity of TiO2 .关键词
