A novel and versatile technique for the facile synthesis of porous.ZnS/Zn nano-particles is developed by laser ablation Zn metal in a.solution containing thioacetamide (TAA), hydrochloric acid (HCl) and.hexadecyl trimethyl ammonium bromide (CTAB). The acid plays a.critical role in the formation of porous surface structures, due to the aciddecomposition of Zn and S ions in the early stage of the nucleation process..Compared with core-shell ZnS/Zn nano-particles, the as-prepared ZnS/Zn.porous structures have enhanced activity in visible-light-driven.photocatalytic reduction of extremely toxic aqueous Cr(VI), because.of the increased surface area and higher pore volume. The present results.have opened up a new paradigm to obtain superior photo-catalyst in.reduction of aqueous Cr(VI) under visible light.
