摘要
在本章中,以丁二酮肟与四水合乙酸镍为原料制备出一种新型的分等级大孔/介孔NiO,再与三聚氰胺混合,通过煅烧成功制备出大孔/介孔NiO/g-C_3N_4复合光催化剂。所制得的样品通过X-射线粉末衍射(XRD)、红外光谱分析(FT-IR)、比表面积(BET)、扫描电镜(SEM)等手段进行了表征。所有样品通过在可见光下降解罗丹明B(RhB)水溶液以评估其催化活性。实验结果表明,当氧化镍和三聚氰胺质量配比为1∶80时,NiO/g-C_3N_4复合材料的光催化活性最高。
In this work,a new type of hierarchical macro/mesoporous NiO was prepared by using the dimethylglyoxime and the nickel acetate as precursors.The obtained hierarchical macro/mesoporous NiO was then mixed with melamine to produce macro/mesoporous NiO/g-C 3N 4 composite photocatalyst via calcination treatment.The samples were characterized by XRD,FT-IR,BET,SEM.The catalytic activity of all samples was evaluated by the degradation of Rhodamine B(RhB)under visible light irradiation.The NiO/g-C 3N 4 composite photocatalysts exhibited the highest photocatalytic acitivity when the mass ratio of NiO to melamine was 1∶80.
