摘要:
以三聚氰胺为前驱体,制备g-C3N4纳米鳞片.采用光沉积法制备不同银含量的高效可见光驱动Ag/g-C3N4异质结光催化剂,并利用X-射线衍射仪(XRD),傅立叶变换红外光谱(FTIR)、扫描电子显微镜(SEM)等手段对催化剂的组成、结构和形貌进行表征.通过比较罗丹明B在可见光下的降解速率,表明异质结对光催化降解效率优于纯g-C3N4,可见光照射120 min,罗丹明B的降解率
Abstract:
Using melamine as the precursor,g-C3N4 nanoscale flakes were prepared.High-efficiency visible light-driven Ag/g-C3N4 heterojunction photocatalysts with different silver contents were prepared by light deposition method,and X-ray diffractometer(XRD),Fourier Transform infrared spectroscopy(FTIR),scanning electron microscopy(SEM)and other means have been used to characterize the composition,structure and morphology of the catalyst.By comparing the degradation rate of rhodamine B under visible light,it is shown that the heterojunction has better photocatalytic degradation efficiency Pure g-C3N4.Irradiated by visible light for 120 min,the degradation rate of rhodamine B reached 95.7%.In addition,the photocatalytic mechanism of the Ag/g-C3N4 heterojunction was analyzed in detail.
