鉍系光催化劑的制備及其對環(huán)境污染物的降解性能研究
[Abstract]:In this paper, a novel and simple anion exchange method is used to realize the conversion of BiOCl to a variety of materials (BiOF, Bi7F11O5 and BiF3). In the process of conversion, the molar ratio of F/Bi is studied. Effects of Fluorine sources and reaction solvents on BiOCl samples .X- ray diffractometer (XRD), scanning electron microscope (SEM), high resolution transmission electron microscope (HRTEM), specific surface area (BET), UV-Vis diffuse reflectance (UV-DRS), fluorescence spectrum (PL) and electrochemical impedance spectroscopy (EIS), etc. Analytical methods are used to characterize the morphology and structure of the product. Furthermore, the conversion mechanism has been proposed and the photocatalytic properties of various catalysts have been studied. Surprisingly, the photocatalytic activity of the resulting Bi7F1FO5/BiOCl complex for the degradation of methyl orange (MO) was three times higher than that of the BiOCl sample. Based on the above experimental phenomena and characterization results, the photocatalytic performance of Bi7F11O5 / BiOCl complex is mainly attributed to the heterojunction of the formed Bi7F11O5/BiOCl complex, and the separation efficiency of photogenerated charge is improved obviously because of the heterojunction of Bi7F11O5 / BiOCl complex. This study provides a simple and effective method for material conversion.
