Z型BiOI/NH2-MIL-125(Ti)复合材料高效光催化降解四环素
Z-scheme BiOI/NH2-MIL-125(Ti)composite for efficient potocatalytic degradation of tetracycline
摘要
Abstract
The Z-type heterojunction BiOI/NH2-MIL-125(Ti)system was formed by loading NH2-MIL-125(Ti)on BiOI nanosheets via the hydrothermal method.X-Ray Diffraction(XRD),Fourier Transform Infrared Spectroscopy(FT-IR),Scanning Electron Microscope(SEM)and Transmission Electron Microscope(TEM)were used to study the crystal structure,functional groups and micro-scopic morphology of the prepared materials.X-ray Photoelectron Spectroscopy(XPS),UV-Vis Dif-fuse Reflectance Spectroscopy(UV-Vis DRS)and Photoluminescence Spectroscopy(PL)were used to analyze its elemental composition and optical properties.Brunauer-Emmett-Teller(BET)theory was used to analyze the specific surface area and pore structure of materials.Tetracycline(TC)was select-ed as the target pollutant to evaluate the photocatalyst activity under visible light.The results showed that BiOI/NH2-MIL-125(Ti)-15 had the best photocatalytic performance,and the degradation rate of tetracycline reached 0.896 within 90 min.After five cycles of degradation experiment,the degradation rate still reached 0.857.Free radical quenching experiments showed that h+and·O-2 were the main active substances in tetracycline degradation.关键词
