以棉花为模板制备生物形态ZnO

Synthesis of Biomorphic ZnO Using Cotton as the Biotemplate

以天然棉花为模板,使用一种简单、环保的技术合成了具有纳米尺度、多孔结构的生物形态ZnO。棉花首先经过硝酸锌溶液浸渍,随后在自然气氛下高温煅烧得到ZnO纤维材料。研究表明,煅烧温度为400℃时,得到的ZnO纤维不但完全去除了作为模板的棉花,而且还保留了棉花的宏观形貌和微观结构特征。

A simple and green technique has been developed to prepare biomorphic porous nano ZnO, using cotton as the template. Cotton is infiltrated with zinc nitrate solution and subsequently sintered in air at high temperature to produce the final ZnO fibers. The results show that when calcined at 400℃ ZnO fibers faithfully retain morphological and microstructural features of the fibrous cotton, and the cotton body is completely removed.
