摘      要：The charge carrier separation efficiency and the adsorption capacity of the photocatalyst usually affect the degradation rate of ***,Cerium-doped leaf-like CdS(Ce-CdS)modified with ultrathin N-doped rGO(N-rGO)composites were successfully constructed(Ce-CdS/N-rGO)to investigate the removal efficiency of tetracycline(TC).X-ray photoelectron spectroscopy(XPS)and photoelectrochemical results revealed that Ce ions doped in CdS acting as the electron capture sites facilitated the interfacial charge *** calculation(DFT)results indicated that the interfacial effect between Ce-CdS and ultrathin N-rGO promoted the transfer of photogenerated electrons under the synergistic effect between the doping and interface modification *** optimized Ce5-CdS/N-rGO20 composites had the maximum TC removal capability(94.5%)and maintained a stable cycling *** addition,the adsorption-driven photocatalytic degradation pathway of TC was studied through mass spectrometry(MS)and in-situ Fourier transform infrared spectroscopy(in-situ FTIR).This study will provide an effective strategy for the construction of efficient photocatalytic composites for wastewater treatment.
