Abstract

ZnS nanoparticles were obtained by the pyrolysis of Zinc (II) complex at 280˚C to generate ZnS nanoparticles. The as-prepared Zn Snanoparticles were further incorporated into the polymer matrices of polyvinyl alcohol (PVA) to generate ZnS/PVA nanocomposites via electrospinning technique. The electrospun fibre (ZnS/PVA) was employed as a catalyst in photocatalytic degradation of methylene blue. The nanofiber was observed to have an impressive ability on photodegradation of methylene blue; as the methylene blue solution became completely colourless when ZnS/PVA was used as catalyst. Fourier transform infrared (FTIR), scanning electron microscope (SEM), and UV-vis spectroscopy were used to characterise the ZnS nanoparticles and ZnS/PVA nanocomposites.
