摘要：In this study, a new nano-Bi2MoO6/calcined mussel shell composite photocatalyst was successfully prepared via a facile solvothermal method. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and UV-vis diffuse reflection spectroscopy (DRS) were employed to investigate the morphology, crystal structure, optical properties. It was shown that the nanometer-scaled Bi2MoO6 crystals was assembled with calcined mussel powder, and forming a similar spheroid structure. The obtained samples were displayed higher photocatalytic activities than pure Bi2MoO6 for the degradation of MB under visible-light irradiation. Among them, the Bi2MoO6/calcined mussel shell mass ratio of 0.7 exhibited the highest activity, and the MB degradation efficiency reached up to 62.46% within 60 min. As a photocatalytic reactor, its recycling performance showed a good stability and reusability. This new composite photocatalyst material holds great promise in the engineering field for the environmental remediation.
