Abstract:
This research aimed to synthesize copper sulfide (CuS) nanocrystal from the solution of CuCl22H2O and Na2S9H2O by hydrothermal method using hexadecyl trimethyl ammonium bromide (CTAB) as a reducing agent for photocatalytic activity. The ratios of copper to sulfur were in molar ratio of 1:6, 1:8 and 1:10. All synthesized catalysts were obtained in an oven at 130C for 24, 48 and 72 hours, respectively. The result of CuS exists as hexagonal phase that was characterized by X-ray diffraction (XRD) and average crystallite size were in range 25 to 500 nm which characterized by scanning electron microscopy (SEM). Energy band gap of prepared CuS nanocrystals were 1.88 - 2.04 eV that were characterized by UV-Vis diffuse reflectance (UV-DRs). The photocatalytic performance for degradation 40 ppm of paraquat solution under visible light was investigated. The kinetic model of photocatalytic degradation of paraquat solution that using prepared CuS (1:8 obtained for 72 hours) was expressed by LHHW and pseudo 1st order, giving rate constant of 2.51x10-3 min-1
