摘要
Visible-light-driven ZnGaNO solid solution–carbon nitride intercalation compound(CNIC) composite photocatalyst was synthesized via a mixing and heating method. The composite photocatalyst was characterized by X-ray diffraction(XRD), field-emission scanning electron microscopy(FESEM), high-resolution transmission electron microscopy(HRTEM), Fourier transform infrared(FT-IR) spectroscopy, UV-vis diffuse reflection spectroscopy, X-ray photoelectron spectroscopy(XPS), photoluminescence(PL) spectroscopy and BET surface area measurements. The activity of ZnGaNO–CNIC composite photocatalyst for photodegradation of methyl orange(MO) is higher than that of either single-phase CNIC or ZnGaNO solid solution. The as-prepared composite photocatalysts exhibit an improved photocatalytic activity due to enhancement for the separation and transport of photo-generated electron–hole pairs.
