Ag₃PO₄/NiO Composites with Enhanced Photocatalytic Activity under Visible Light.

ABSTRACT: Black NiO powders were prepared by a hydrothermal method. Moreover, the visible light-driven Ag₃PO₄/NiO photocatalyst composites were successfully synthesized by in situ precipitation method. These samples were structurally characterized by X-ray diffraction and Rietveld refinement. The strong interaction between the phases and the defects in the samples was affected by the formation of the composites, as identified by Fourier transform infrared spectroscopy and Raman spectroscopy. UV-vis diffuse reflectance spectroscopy exhibited enhanced light absorption for all Ag₃PO₄/NiO composites, suggesting the effective interaction between the phases. Moreover, field-emission scanning electron microscopy images revealed the presence of NiO microflowers co
