摘　　要：利用分子氧和溴酸钾一步直接在溶液中氧化还原反应原位产生碱作为氧源来制备纳米结构ZnO。首先,在甲酰胺水溶液中,以锌箔作为锌源,在温和条件下分别合成了纳米棒/管构成的海蛰状ZnO。其次,在溴酸钾水溶液,以锌箔作为锌源,在近室温下合成了纺锤形ZnO。该方法具有反应条件温和,反应参数连续可调节,一步湿法直接合成的ZnO具有新颖微/纳米结构等优点。A simple low-temperature strategy had developed for the low-cost and large-area fabrication of different ZnO nanostructures by the natural oxidation of zinc metal. Urchin-like ZnO built up of nanorod/tube were synthesized in formamide and potassium bromate aqueous solution at near room temperature through simple chemical-liquid-deposition process. The possible formation mechanisms of these unique micro/nanostructures were also presented. It was a direct, mild and practical strategy for the low cost and large-scale fabrication of high-quality ZnO nanostructures with predictable morphologies through continuously tunable reaction parameters.
