Abstract

The current research work investigated the photocatalytic degradation of dye using polythiophene-based silver-doped zinc sulfide (PT/Ag-ZnS). The ternary composite was synthesized by in-situ chemical oxidation polymerization approach and thoroughly characterized. Maximum photocatalytic activity depicted > 80% for Ag-ZnS and > 94% for PT/Ag-ZnS at pH 7 and 4 respectively at 10 mM oxidant and 30 mg/100 mL catalyst dose, 10 ppm IDC under 90 min. DMSO serves as an effective radical scavenger. The novel polymeric composite exhibits efficient reusability upto five cycles. Pseudo 1^st -order kinetic model was best fitted for PT/Ag-ZnS. Toxicity analysis gave a green clue of treated water.
