Abstract
In this project, the Au and Ce co-doped SnS2 decoration on hyperbranched polyethyleneimine (Au/Ce/SnS2/HPEI) nanocomposites were prepared via wet/hydrothermal chemical method. Compared with pure SnS2 and co doped SnS2, Au/Ce/SnS2/HPEI nanocomposite indicated higher photo-degradation performance for the reduction of chromium (VI) under visible light irradiation. Therewith, Au/Ce/SnS2/HPEI nanocomposites was applied for photo-degradation of drug. The possible mechanism shows the superoxide anion radical (O2−) plays important role in in the removal of Cr(VI). The Au/Ce/SnS2/HPEI nanocomposites shows the best photocatalysis activity for water reduction. The prepared Au/Ce/SnS2/HPEI displayed excellent antifungal activity against Aspergillus niger and Candida albicans fungi.
