摘要
为了弄清复合光催化剂ZnO/CoO/g-C_(3)N_(4)的制备和性能,采用XRD和SEM对材料进行表征和分析,研究了煅烧温度和ZnO/CoO与g-C_(3)N_(4)质量比的影响。以亚甲基蓝(MB)作为模拟污染物,研究了ZnO/CoO/g-C_(3)N_(4)的光催化性能,并通过电化学工作站研究了其电化学性能。结果表明:煅烧温度为550℃、ZnO/CoO与g-C_(3)N_(4)的质量比为1∶0.5的样品XRD效果最好;与单一或双组分体系相比,ZnO/CoO/g-C_(3)N_(4)三组分复合体系具有更好的光催化和电化学性能。
In order to clarify the preparation and properties of the composite photocatalyst ZnO/CoO/g-C_(3)N_(4),XRD and SEM were used for material characterization and analysis,and the effects of calcination temperature and different mass ratios of ZnO/CoO and g-C_(3)N_(4)were studied.The photocatalytic property of ZnO/CoO/g-C_(3)N_(4)was investigated by using methylene blue(MB)as a simulated pollutant and its electrochemical property was studied by an electrochemical workstation.The results show that the XRD effect of the sample with a calcination temperature of 550℃and a mass ratio of ZnO/CoO∶g-C_(3)N_(4)of 1∶0.5 is the best.The three-component composite system of ZnO/CoO/g-C_(3)N_(4)has better photocatalytic and electrochemical properties compared to single or two-component systems.
