Abstract: ZnS nanoparticles implanted with 45 keV O5+ ion beam exhibited 83.6% degradation of methyl blue in 2h. This idea was utilized to fabricate nanocomposite system of ZnS and PMMA where ZnS nanoparticles were immobilized in PMMA film and irradiated with 45 keV O5+ ion beam at particle fluence of 2.5 × 1015, 1 × 1016 and 4 × 1016 particles/cm2. These irradiated batches of ZnS nanoparticle immobilized in PMMA batches revealed formation of porous structure characterized by scanning electron microscopy and these batches exhibited 54% photocatalytic degradation of methyl blue in 80 min which was higher as compared to the pristine ZnS nanoparticles. © Akadémiai Kiadó, Budapest, Hungary 2014.
