Facile photocatalytic reduction of carcinogenic Cr(vi) on Fe-doped copper sulfide nanostructures.

In this study, Fe-doped copper sulfide nanoparticles (NPs) were investigated for the solar-assisted reduction of Cr ions in raw water. The Fe-doped NPs were synthesized by decomposing copper(ii) ,-diphenylmethylpiperazinecarbamodithioate a facile single-step, one-pot solvothermal method in the presence of iron salt. The Cr photoreduction data were fit to a pseudo-first-order kinetic model and a Langmuir model.
