چکیده
The application of nanocatalysts for the removal of dyes from industries' wastewater and effluents has attracted great attention these days. In this paper, CdTe/CdS/ZnS core/multi-shell quantum dots were used as a nanocatalyst for the degradation and removal of methylene blue, methylene orange, and rhodamine b dyes from water. The obtained results showed that CdTe/CdS/ZnS nanocatalyst had excellent ability for removal of methylene blue dye from water and after 60 min reaction time, methylene blue dye was completely degraded (100%). Also, the degradation percentage of rhodamine b and methylene orange dyes was obtained at about 80.2% and 55.2%, respectively. The radical scavenger experiment was used to study which active radicals play a key role in the photocatalyst process of CdTe/CdS/ZnS nanocatalyst with methylene blue dye and results showed that electrons play a key role in the degradation process. The successful formation of CdTe/CdS/ZnS core/multi-shell QDs was studied by XRD, EDS, PL, absorbance, and TEM analysis.
