Scholarcy highlights

  • The recycling experiments proved the stability, catalytic activity and reusability of composites in degrading the dye solution
  • The flower-like CuS/RGO composites were synthesized via a facile one-pot solvothermal method, which displayed outstanding photocatalytic activity for Methylene blue(MB) degradation under Xenon lamp irradiation
  • The as-prepared samples were e examined by X-ray diffraction, X-ray photoelectron spectroscopy, photoluminescence(PL) spectra, scanning electron microscopy, transmission scanning electron microscopy and UV–vis optical absorption spectroscopy to determine the properties of the samples, respectively
  • The results illustrated that RGO had an important effect on the photocatalytic performance of CuS/RGO for dyes
  • The photocatalytic degradation efficiency of MB reached up to nearly 80% after 140 min irradiation, which was more than four times higher than that of CuS, indicating that CuS/RGO composites could have a great potential application in organic pollutants removal
