Synthesis of Fe-CuS/RGO by solvothermal method with high visible photocatalytic activity
The Fe element doped CuS/RGO(Fe-CuS/RGO) was fabricated via a facile one-step solvothermal method, which displayed outstanding photocatalytic activity for MB degradation.The composition and structure of the prepared composites were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectra,photoluminescence(PL) spectra, scanning electron microscopy (SEM), Transmission electron microscope(TEM) and UV-vis optical absorption spectroscopy.The results showed that pristine CuS, CuS/RGO and Fe-CuS/RGO exhibited photocatalytic activity for the photodegradation of Methylene blue(MB) with degradation efficiency of 41.2%、 81.5% and 90.6%, respectively, in 140min under Mercury lamp irradiation, indicating that Fe-CuS/RGO could be acknowledged as a promising photocatalyst for the removal of organic contaminants.The enhanced photocatalytic activity was ascribed to that Fe element could be acted as an interracial charge transfer channel between CuS and RGO to thus inhibit the recombination of photogenerated electron-holes pairs.
