One-pot synthesis optimization of thiol-capped SnS and SnS/ZnS QDs for photocatalytic degradation of Rhodamine 6G.

ABSTRACT: Interest in SnS-based quantum dots (QDs) has increased due to their low toxicity, widespread natural availability, and superior electro-optical characteristics suitable for photodegradation applications. Herein, we report the synthesis of SnS-based QDs using thiourea and tin (II)chloride as salt precursors. The study explored the impact of various synthetic parameters such as pH, capping ligand, Sn:S ratio, reaction solvent, and ZnS shell on the optical characteristics of the synthesized QDs. The optimal QDs properties were observed at pH = 3 and Sn:S ratio = 1:1. Transmission electron microscopy analysis showed spherical nanoparticles, while the Fourier Transform Infrared spectroscopy revealed QDs with thiol capping. Time-dependent studies revealed that when the QDs were synthesized using
