Abstract
It is the need of era to develop contender to utilize in degradation of the environmental pollutant by solar energy. Photocatalysis is a promising and ideal technology for environmental remediation. A facile approach to prepare ZnO nanoparticles and doping influence on structures and photocatalytic properties of ZnO nanostructures at optimum concentration is presented. Moreover, enhanced photocatalytic performances making composite with sulphur doped g-C3N4 is also presented. Cobalt is used as dopant on ZnO nanostructures. Undoped and doped (0.1%,0.5%,1%,2%,4%) doped nanoparticles were prepared by wet chemical and annealing was done at 550˚C with 3˚C/minute ramping rate for 3 hours. Sulphur doped graphitic carbon nitride nanosample was prepared by using thiourea. Nanocomposites of sulphur doped graphitic carbon nitride with cobalt doped zinc oxide were prepared. Various kinds of characterization techniques were used to analyze the structural properties like Scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier Transform Infrared spectroscopy (FTIR). Photocatalytic response of all the samples was done by the degradation of methylene blue (MB), employed as organic pollutant. Photocatalytic activity was checked by UV-Vis spectrophotometer. Solar light was used for UV-Visible light irradiation. For degradation of waste dyes these nanocomposites are new attractive candidates.
