摘要：
SiO2-CNFs composites were prepared by electrospinning and calcination with change of the dosage of SiO2 nanoparticles into electrospinning precursor solution. CuS nanosheets were controllably grown on the surface of SiO2-CNFs through hydrothermal method, which was characterized by SEM, FTIR, TEM, XRD, and XPS techniques. The results showed that multi-hydroxyl on the surface of SiO2 provided active sites to attract Cu2+. Hence, SiO2 modified CNFs had the function of directional anchoring CuS nanosheets. The photocatalytic degradation of tetracycline using CuS-SiO2-CNFs was further investigated. Compared with CuS-CNFs and CuS-2%SiO2-CNFs samples, the CuS-1%SiO2-CNFs had the optimal photocatalytic activity, which was attributed to that CuS nanosheets were homogeneously dispersed on the surface of 1%SiO2-CNFs.
