摘要
通过一步微波辅助法合成Ag/Cu xCo 1-x Fe 2O 4/RGO复合光催化剂.通过X-射线衍射(XRD)、傅里叶变换红外光谱(FTIR)、扫描电镜(SEM)、能量色散谱(EDS)、元素面分布(Mapping)及热重分析(TGA)等手段对复合光催化剂进行表征,并对其光催化降解亚甲基蓝的吸附性能进行研究.研究结果表明,在紫外光照射下,Ag/Cu xCo 1-x Fe 2O 4/RGO具有光催化降解MB的吸附性,Co 2+代替Cu 2+时,光催化活性会有所提升.
In this paper,Ag/CuxCo1-xFe2O4/RGO composite photocatalyst was synthesized by one-step microwave assisted method.The photocatalyst was characterized to study its structure and morphology by X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FTIR),Scanning electron microscope(SEM),Energy-dispersive spectroscopy(EDS),Elemental surface distribution(Mapping)and thermogravimetric analysis(TGA).Meanwhile,its adsorption performance in photocatalytic degradation of methylene blue was studied in depth..The results showed that under UV irradiation,Ag/CuxCo1-x Fe2O4/RGO had the photocatalytic degradation of MB,and the photocatalytic activity of Co 2+was improved when Co 2+was substituted for Cu 2+.
