Title: Cellulose/Polyvinylpyrrolidone-doped cadmium sulphide quantum dots and their applications
Abstract: 
In the current work, control sized cadmium sulphide (CdS) quantum dots (QDs) and cellulose nanocrystals grafted polyvinylpyrrolidone (CNC-g-PVP) doped CdS QDs were generated via co-precipitation. Both types of CdS QDs exhibited excellent optical properties. The proposed method is effective in ridding industrial water and bactericidal treatments of organic contaminants such as methylene blue (MB). In order to determine the structural, optical, and morphological properties of the produced samples, a number of different characterization procedures were utilized. The X-ray diffraction (XRD) pattern confirmed the structure to be hexagonal, and there was no discernible shift in the spectrum as a result of the addition of 2, 4, or 6% doping. Doping causes a blueshift in the absorption pattern, which is described by the UV–vis spectrophotometer. This shift leads to an increase in band gap energy (Eg). In comparison to the acidic medium, the findings of the catalytic activity (CA) against MB in basic and neutral media were impressive. In addition, the bactericidal potential of the doped sample (6%), which was tested against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli), both of which are Gram-positive bacteria, exhibited significantly higher inhibition zones. These zones measured 5.25 mm and 4.05 mm, respectively.
