Eu/g-C3N4材料制备及光催化性能
Preparation of Eu/g-C3N4 and Its Photocatalytic Properties
摘要
Abstract
Using europium nitrate hexahydrate as the europium source,Eu/g-C3N4 photocatalytic material was prepared via a straightforward one-step calcination method.The crystal structure,morphology,and elemental dis-tribution of the material were characterized by XRD,SEM,EDX,FT-IR,PL,and UV-vis,and its optical properties were analyzed.Additionally,an electrochemical workstation was employed to test the material's electrochemical performance.Under simulated natural light generated by a xenon lamp,the photocatalytic performance of the material was evaluated through the degradation of ofloxacin.The results indicate that the synthesized Eu/g-C3N4 exhibits a layered structure with dense porosity,and the Eu element is uniformly distributed across its surface.Doping modification led to a red shift in the absorption edge of the material.The degradation rate of ofloxacin by Eu/g-C3N4 was significantly higher than that by g-C3N4,with the sample containing 0.07 g of europium nitrate showing the optimal performance.The photocatalytic efficiency of Eu/g-C3N4 in degrading ofloxacin was 3.8 times that of pure-phase g-C3N4.关键词
