摘要: The growth of hollow tubes, nanowire array, and segmented porous arrays made Cu–Zn alloys in a Lewis acidic ZnCl2-1-ethyl-3-methylimidazolium chloride ionic liquid via direct electrodeposition without the need for template is presented. formation each type structure described. Hollow tubes result from uneven overpotential gradient created at low Cu(I) concentration applied deposition overpotential. Nanowire form under mass-transport-limited conditions, which speciation plays an important role. Segmented are obtained by increasing to enhance profile vibration near surface. electrodeposited show very good efficiency electrocatalytic reduction nitrate ions alkaline aqueous solution.
