Abstract

ABSTRACT: A new ZnFe2 O4 /Ag/g-C3 N4 nanosheets composite was synthesized by thermal polymerization combined with photoreduction and solvent thermal followed by calcination. The structure specification, surface composition, and optical absorption properties of as-prepared photocatalysts were characterized by X-ray diffraction, XPS (X-ray photoelectron spectroscopy) spectrum; transmission electron microscopy and UV-vis diffuse reflectance spectroscopy. The photocatalytic activity of the as-prepared photocatalysts was demonstrated by degradation of rhodamine B (RhB) solution under xenon lamp irradiation. It was confirmed by chemical capture experiments that ·O2 – and h+ are the main active species in the degradation of Rhodamine B. The unique Z-scheme structure of ZnFe2 O4 /Ag/g-C3 N4 has been the basis for enhanced photocatalytic activity. The newly synthesized catalyst has better photocatalytic activity, good safety, and easy recycling.
