摘　　要：在导电塑料聚偏氟乙烯(PVDF)中引入TiO2和氧化石墨烯(GO),制备了PVDF/TiO2/GO复合材料。由于PVDF的引入显著提高了TiO2的分散性,并且GO作为优良的电子接收器,可以有效地提高光生电子空穴分离效率。研究结果表明:PVDF/TiO2/GO复合材料对太阳光具有较好的利用率,在不同光源下对四环素(TC)均具有较好的祛除效率,并且在降解过程中主要的活性物种为光生电子。PVDF/TiO2/GO composites were prepared by introducing TiO2 and graphene oxide(GO)into conductive plastic polyvinylidene fluoride(PVDF).The introduction of PVDF significantly improves the dispersion of TiO2,and GO as an excellent electron receiver can effectively improve the efficiency of photo-generated electron hole separation.The results show that the PVDF/TiO2/GO composite has good utilization of sunlight,and has good removal efficiency for tetracycline(TC)under different light sources,and the main active species in the degradation process are photogenerated electrons.
