摘要：

Carbon quantum dots (CQDs)/CdSe/reduced graphene oxide (rGO) was fabricated by hydrothermal method. The structures, optical and electronic properties of as-obtained photocatalysts were analyzed by transmission electron microscopy (TEM), X-ray diffraction (XRD) and photoelectrochemical testing. The photocatalytic performances were investigated by degradation of tetracycline hydrochloride (TC center dot HCl). The results showed CQDs modified CdSe loaded rGO could effectively remove TC center dot HCI, the CdSe modified with 7 mL CQDs showed higher photocatalytic degradation rate; the 5 wt% loaded rGO for CQDs/CdSe showed highest photocatalytic activity. The photocatalytic mechanism exhibited (OH)-O-center dot, O-2(center dot-) and 10(2) radicals play key roles. (C) 2017 The Korean Society of Industrial and Engineering Chemistry.
