Abstract
Indium (In)-doped copper sulfide (CuS) nanostructure were synthesized by the sonochemical method. The results of X-ray diffraction (XRD) showed that the CuS nanostructure had a hexagonal covellite structure. Field emission scanning electron microscopy (FESEM) images showed a decrease in the size of particles after the doping by In. Moreover, the morphology of the nanoparticles (NPs) was changed from a nanoparticle to flake shape. Energy-dispersive X-ray (EDX) analysis also confirmed the presence of a dopant in the synthesized products. The transmission electron microscopy (TEM) studies confirmed the effect of indium ions on the morphology of CuS nanostructure. UV–Vis analysis showed that the optical energy band gap changed in the presence of In doping. The photocatalytic degradation analysis proved that the products have a higher percentage of degradation after doping.
