Abstract
The g-C3N4/BiNbO4@AgI ternary composite catalyst was successfully prepared by the in-situ growth method. The structure and micro-morphology of the catalyst were analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and Field emission scanning electron microscope (FE-SEM). The element composition and valence state of the catalyst were analyzed by energy spectrum analysis (EDS) and X-ray photoelectron spectroscopy (XPS). It is found that the catalyst has good dispersibility and no impurities. Visible light catalytic degradation of rhodamine B (RhB) experiment results show that the 30 wt % g-C3N4/BiNbO4@AgI ternary composite catalyst has the best photocatalytic activity. Cycling experiments found that the catalyst has good stability. Combined with the capture experiment of active free radicals, the possible photocatalytic degradation mechanism of the 30 wt % g-C3N4/BiNbO4@AgI ternary composite catalyst was speculated.
