  • 摘要: 通过一步水热法制备了光催化剂CuxZn1-xS/RGO，实现了CuxZn1-xS纳米颗粒的可控生长和氧化石墨烯（GO）还原的同步进行，并将所制备的CuxZn1-xS/RGO用于环丙沙星（CIP）的催化降解研究.采用X-射线衍射（XRD）、电感耦合等离子体-原子发射光谱仪（ICP-AES）、傅立叶变换红外光谱（FTIR）、紫外可见漫反射光谱（UV-Vis）、电子显微镜（SEM）和透射电子显微镜（TEM）对复合物的组成形貌进行表征.结果表明，球状的CuxZn1-xS颗粒成功负载在石墨烯表面.Cu2+的掺杂增强了CuxZn1-xS/RGO光催化剂在可见光范围的响应，石墨烯的引入抑制了CuxZn1-xS纳米颗粒的团聚，提高了光催化性能.此外，Cu0.1Zn0.9S/RGO10对CIP的降解速率分别是ZnS、Cu0.1Zn0.9S的8倍和4.4倍.
    Abstract: A facile approach to prepare CuxZn1-xS/RGO photocatalyst was developed via a one-step hydrothermal synthesis. Formation of CuxZn1-xS nanoparticles and the reduction of graphene oxide (GO) were achieved simultaneously in the synthesis process. The degradation of ciprofloxacin (CIP) catalyzed by CuxZn1-xS/RGO composite was investigated. The composites were characterized by X-ray diffraction (XRD), inductively coupled plasma-atomic emission spectrometer (ICP-AES), Fourier transform infrared spectroscopy (FTIR), ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis), scanming electron microscopy (SEM) and transmission electron microscopy (TEM). The characterization results showed that spherical CuxZn1-xS nanoparticles were tightly attached to graphene. Doping of Cu2+ enhanced the response of CuxZn1-xS/RGO photocatalyst in the visible light range. The introduction of graphene inhibited the agglomeration of CuxZn1-xS nanoparticles and improved the photocatalytic performance. In addition, the photocatalytic degradation rate of Cu0.1Zn0.9S/RGO toward CIP was almost 8 times the rate of ZnS and 4.4 times that of Cu0.1Zn0.9S, respectively.
