The hierarchical flower-like CuS microspheres with high surface area were synthesized by a simple solvothermal method at 170 °C for 5 h, employing copper chloride (CuCl2 · 2H2O) as Cu-source, thiourea (CH4N2S, Tu) as S-source and 1,2-propanediol(1,2-PG) as the solvent. X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-Vis absorption spectra and Fourier transform infrared (FTIR) spectroscopy were used to characterize the as-prepared CuS. And the photocatalytic performance of the obtained flower-like CuS was evaluated by the degradation of Direct blue 2B, Direct blue 86, Methylene blue, Cationic Red X-5GN, Cationic yellow SD-5GL solution under ultraviolet/visible irradiation. The experimental results demonstrated that the as-prepared flower-like CuS presented remarkably enhanced photodegradation activity for dye even with the absence of H2O2 and further the CuS showed more better visible-light-driven photocatalytic activities for degradation of dye. In addition, no significant loss of photocatalytic activity on photodegradation of mentioned dye was observed after five recycles experiments, which further proved the as-obtained CuS with stable recycling performance.
