多孔碳BVO/Zn@ZPC的制备及其光降解性能
Preparation and Photodegradation Performances of Porous Carbon BVO/Zn@ZPC
摘要
Abstract
Degradation of tetracycline(TC)is a challenge in the process of water pollution.A porous carbon material Zn@ZPC was obtained via direct roasting of ZIF-8 precursor and BiVO4(BVO)was prepared by a hydrothermal method.Subsequently,a hybrid BVO/Zn@ZPCcomposites were prepared by in-situ heat treatment of Zn@ZPC and BVO.Meanwhile,the effects of the addition amount of BVO and roasting temperature on catalyst properties and photocatalytic performance were discussed in the process.The morphology and structure of the photocatalysts,the state of the metal species,and the pore structure were analysed by XRD,SEM,TEM,XPS,N2 adsorption-desorption,UV-vis DSR,and ESR techniques,respectively.The results showed that a Z-type heterojunction was formed between ZnO and BVO.In the experiments of photodegradation of tetracycline,BVO-40/Zn@ZPC-600 with a roasting temperature of 600℃and a BVO additive amount of 40 mg had the best photocatalytic degradation performance:under the irradiation of visible light,5 mg of the catalyst was able to completely degrade 100 mL TC(50 mg/L)within 60 min.关键词
