Abstract

Cadmium Sulphide (CdS) Quantum dots (QDs) has been synthesised by using precipitation method. Structural and morphological characteristics of CdS QDs were measured by XRD, FT-IR, and FESEM techniques. The thermal properties of nanomaterial were also studied by thermogravimetric and differential scanning calorimetry. The optical band gap was calculated by using Tauc plot. The synthesised material was employed as a photocatalyst for the degradation of 2-chlorophenol (2-CP) under UV light irradiation. The impact of pH for photodegradation of the catalyst has also been investigated and shows higher efficiency at high pH. The photodegradation efficiency was found to be 80% with increasing amount of catalyst. Antimicrobial activities against E. coli and Aeromonas hydrophilia were also performed by this CdS QDs. This work demonstrates the potential applications of CdS for photodegradation and antimicrobial activity.
