Exploring the Potential of ZnS/CdS Dual Nanocomposites in Photocatalytic Degradation for Water Cleanup

The use of photocatalytic degradation to address environmental cleanup issues is gaining popularity. in this work, pure zns, cds, and zns/cds heterostructure nanocomposites with superior photocatalyst efficiency were synthesized using a straightforward coprecipitation technique and a solvothermal process. the structural, morphological, and optical characteristics were analyzed using xrd, edx, ftir, fesem, and uv-vis absorbance measurement techniques. the xrd data indicated that zns/cds nanocomposites were produced with an average crystallite size of 15–20 nm. the uv-vis measurements revealed an optical band gap ranging from 4.4 ev to 5.3 ev. the photocatalytic efficacy of the zns/cds heterostructure nanocomposites in degrading methylene blue (mb) dye was evaluated under uva light. the synthesized zns/cds nanocomposite exhibited remarkable decolorization efficiency (99%) within just 5 minutes of uva light exposure. this straightforward method has the potential to be scaled up for industrial applications.
