“…Semiconductor quantum dots have been investigated as efficient photocatalysts, because of their numerous advantages including excellent photoabsorption properties in the UV‐Vis region and size‐tunable band structure. ZnS, is a direct bandgap semiconductor belonging to the II–VI class group, is a good choice of a photocatalyst, due to its comparatively less toxic nature . One major drawback of using ZnS QDs is its irreversible agglomeration behavior during the isolation or photocatalytic reactions which largely affects its photocatalytic degradation efficiency.…”

“…The dye concentration is the additional key parameter that needs to be considered, as the process’s efficacy is affected tremendously by it [ 83 ]. In this context, the effect of variation of initial dye concentration from 20 to 50 mg/L was investigated.…”

“…The resulting data could be rationalized because more organic substances made it impossible for the system to perform well as dye concentration increased. In addition, increasing the dye concentration weakened the pathway for photons incoming into the solution, thus lessening the photonic absorption on the rGO surface and reducing dye degradation efficacy [ 83 ].…”

“…However, this material has also some disadvantages, such as photo-corrosion or photo-dissolution, that may restrict its stability and applicability. The defects of CdSe QDs can be improved by further modification using some capping-ligands (Ma et al 2015;Mahmoodi et al 2016). The unique properties that make QDs Fig.…”
