Highly efficient reduction of aqueous Cr(Ⅵ)with novel ZnO/SnS nanocomposites through the piezoelectric effect
文献摘要:
In this work,novel ZnO/SnS nanocomposites were successfully synthesized via a hy-drothermal approach,which is developed for piezoelectric catalytic reduction of hexavalent chromium(Cr(Ⅵ))in an aqueous solution.The constructed ZnO/SnS nanocomposites exhib-ited higher catalytic efficiency for Cr(Ⅵ)reduction under a mechanical force(e.g.,ultrasonic vibration)compared to pristine ZnO and SnS.In particular,the ZnO/SnS(with 30 wt.%of SnS)heterojunctions revealed an optimal degradation activity among all the prepared sam-ples,which completely removed the Cr(Ⅵ)(20 mg/L)solution within 35 min.Moreover,the piezoelectric catalytic activity of ZnO/SnS remained stable after four consecutive cycling experiments.The results of the morphology observations indicated that the SnS nanopar-ticles adhere to the surface of the ZnO nanorods.The improved piezoelectric catalytic per-formance of the ZnO/SnS heterojunctions can be attributed to the formation of an intimate interfacial between ZnO and SnS,which effectively inhibits the electron-hole recombina-tion and speeds up the rate of charge transfer.The study reveals a new design of ZnO/SnS heterojunctions as a high-performance and eco-friendly piezoelectric catalyst and provides a promising strategy for addressing environmental problems and energy crises.
