摘要:

纳米材料的紫外屏蔽性能及光催化性能会由于材料自身的表面结合能不同而不同。制备纳米氧化锌(NPs?ZnO)、纳米二氧化铈(NPs?CeO2)、NPs?ZnO/CeO2及氧化石墨烯改性氧化锌/氧化铈纳米复合材料(NPs?ZnO/CeO2@GO),并对制备样品进行了XRD、FT?IR、SEM等表征和紫外屏蔽性能及光催化性能测试研究。结果表明,紫外屏蔽能力:NPs?ZnO<NPs?CeO2<NPs?ZnO/CeO2<NPs?ZnO/CeO2@GO,作用3 h后的亚甲基蓝染料的降解率大小顺序为:NPs?ZnO/CeO2@GO(0.92)>NPs?ZnO(0.89)>ZnO/CeO2(0.75)>NPs?CeO2(0.66);并且NPs?ZnO/CeO2@GO的光催化性强于参与实验的其他光催化剂。

Abstract:

The UV shielding properties and photocatalytic properties of nanomaterials will vary due to the different surface binding energies of the materials themselves.Nano?zinc oxide (NPs?ZnO),nano?ceria (NPs?CeO2), NPs?ZnO/CeO2 and graphene oxide modified zinc oxide/ceria nanocomposites (NPs?ZnO/CeO2@GO) were prepared,and the prepared samples were characterized by XRD,FT?IR,SEM,and the UV shielding properties and photocatalytic properties were tested. The results show that the UV shielding ability: NPs?ZnO<NPs?CeO2<NPs?ZnO/CeO2<NPs?ZnO/CeO2@GO, the maximum degradation rate of methylene blue dye after 3 h treatment is:NPs?ZnO/CeO2@GO(0.92)>NPs?ZnO(0.89)>NPs?ZnO/CeO2(0.75))>NPs?CeO2(0.66).Moreover,the photocatalytic activity of NPs?ZnO/CeO2@GO is stronger than other photocatalysts participating in the experiments.
