摘要
以Zn(CH3COO)2·H2O和NH4HCO3为原料,以室温固相反应和微波辐射技术相耦合的方法制备出粒径在19nm左右的ZnO光催化剂,同时以活性艳兰KN-R为模拟染料废水考察了所制备纳米ZnO的光催化性能。结果表明,所制备纳米ZnO具有良好的光催化活性,在适宜的操作条件下,活性艳兰KN-R的脱色率在96%以上,COD的去除率在69%以上。此外,在染料的浓度为30～100mg/L时,ZnO/UV体系光催化降解活性艳兰KN-R符合一级反应动力学模型。
Nanosized ZnO photocatalyst with particle size of 19 nm was synthesized through the coupled method of solid state reaction at room temperature and microwave irradiation technology by using Zn(CH3COO)2·H2O and NH4HCO3 as raw materials. The photocatalytic performance of the preparing nanosized ZnO was investigated through the degradation of simulated wastewater of Reactive Brilliant Blue KN-R. Results showed that the preparing nanosized ZnO exhibited the good photocatalytic activity. Under the suitable operat...
