Abstract

In this work, a kind of cubic ZnFe2O4 and ZnFe2O4?x wt% graphene (x?=?1, 2, 3, 4 wt% GR) with spinel nano-structure as nano-photocatalytic activity under visible light radiation were prepared by a facile sol?gel method. The structure, surface morphology, chemical composition of nano-powders and nano-hybrids were studied using scanning electron microscopy with an energy dispersive X-ray, X-ray diffraction (XRD), Fourier transform infrared spectroscopy, photoluminescence spectra and vibrating sample magnetometer spectroscopy. XRD results showed that nano-hybrids and nano-particles all the diffraction peaks agree well with to a cubic structure of the ZnFe2O4 spinel (JCPDS No. 22-1010). The particle size of all the compositions are in the range of ∼ 85?95 nm. The ZnFe2O4 nano-powders alone is photocatalytically inactive under visible light irradiation, the combination of ZnFe2O4 nano-powders with graphene nano-sheets leads to high nano-photocatalytic activity for the degradation of Paracetamol drug under visible light irradiation.
