The fabrication of hollow spherical copper sulfide nanoparticle assemblies with 2-hydroxypropyl-β-cyclodextrin as a template under sonication

2-Hydroxypropyl-β-cyclodextrin was used as a template to fabricate hollow spherical copper sulfide nanoparticle assemblies in the presence of sonication. The as-prepared spheres were uniform in shape and have well-defined shells composed of one-layered CuS nanoparticles. The interaction between the Cu ions and HP-β-CD was confirmed by the FTIR. The effects of the sonication were studied and a possible self-assembly mechanism was discussed.
