Abstract

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. Graphical Abstract

期刊介绍： Materials Research Innovations covers all areas of materials research with a particular interest in synthesis, processing, and properties from the nanoscale to the microscale to the bulk. Coverage includes all classes of material – ceramics, metals, and polymers; semiconductors and other functional materials; organic and inorganic materials – alone or in combination as composites. Innovation in composition and processing to impart special properties to bulk materials and coatings, and for innovative applications in technology, represents a strong focus. The journal attempts to balance enduring themes of science and engineering with the innovation provided by such areas of research activity.
