| Abstract: Herein, Bi2MoO6/CoMoO4 embroidery ball structures were synthesized by a simple one-step hydrothermal method that using bismuth nitrate pentahydrate as the bismuth source. By X-ray powder diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), Fourier infrared spectroscopy (FT-IR), ultraviolet-visible diffuse reflection spectroscopy (UV-Vis DRS), fluorescence spectrum (PL), and electrochemical tests were performed to analyze the phase composition, micromorphology, optical properties, and recombination rate of photogenerated charge of the prepared catalyst. The results showed that when introducing Bi2MoO6, the light absorption range of the Bi2MoO6/CoMoO4 heterojunctions were significantly enhanced, and the separation of photogenerated charges were also improved. Methylene blue and ceftriaxone sodium were used as pollutants to simulate wastewater, and the photocatalytic degradation activity of the catalyst samples was evaluated under visible light. After irradiation for 60 min, the composite with Bi2MoO6 loading of 30%(w/w) composites has the best photocatalytic performance, and the degradation rate constant was twice that of pure CoMoO4. Based on all the experimental characterizations, the corresponding photocatalytic mechanism of the Bi2MoO6/CoMoO4 system was further studied. |
