g-C3N4/Bi20TiO32/Bi2O2CO3复合光催化剂降解盐酸四环素
Degradation of Tetracycline Hydrochloride by g-C3N4/Bi20TiO32/Bi2O2CO3 Composite Photocatalysts
摘要
Abstract
To improve the shortcomings of single graphitic carbon nitride(g-C3N4)with high electron-hole complexation and poor photocatalytic performance,in this current study,Bi20TiO32/Bi2O2CO3 was used to modify g-C3N4,and the compos-ites were prepared by ultrasound assisted-high temperature calcination.The structure and microscopic morphology of the composites were investigated by X-ray diffractometer,scanning electron microscopy and transmission electron microscopy to demonstrate the successful preparation of the composites,and the photoelectrochemical properties of the composites were investigated by electrochemical impedance spectroscopy.Then,the photocatalytic performance of the composites was inves-tigated using tetracycline hydrochloride as the removal subject.The experimental results indicated that g-C3N4/Bi20TiO32/Bi2O2CO3 exhibited superior photocatalytic activity compared with g-C3N4 and Bi20TiO32/Bi2O2CO3 under visible light ir-radiation,achieving a photocatalytic degradation rate of 86.1％.Furthermore,the photocatalytic performance of the material remained stable after five cycles of experiments,demonstrating the stability of the composites.关键词
