Abstract
Photocatalysis is one of the most powerful tools for the degradation of dyes and textile waste water. Heterogeneous photocatalyst like TiO2, ZnO, CdS, and CdSe are mostly used semiconductor Quantum dots (QD’s). Biocompatible ZnSe QD’s with the direct band gap 2.7eV were synthesised by hydrothermal route. The as-synthesised biomolecule capped ZnSe QDs were characterized by UV-visible, FT-IR, PL, XRD and SEM. The photocatalytic degradation of Methyl Red (MR) in aqueous solution was monitored at 456nm. Hence this study paves a way to use this biocompatible photocatalyst for the treatment of textile dye industry wastewater under solar light irradiation.
