采用棉花模板制备生物形态Co3O4
Synthesis of Biomorphic Co3O4 Using Cotton As Biotemplate
【摘要】 以天然棉花为模板,经硝酸钴溶液浸渍后在自然气氛下高温煅烧得到具有纳米尺度、多孔结构的生物形态Co3O4纤维材料。研究表明:煅烧温度为600℃时,得到的Co3O4纤维不仅完全去除作为模板的棉花,而且还很好地保留了棉花的宏观形貌和微观结构特征。
【Abstract】 A simple and green technique has been developed to prepare biomorphic porous nano-Co3O4 using cotton as the template.Cotton is infiltrated with zinc nitrate solution and subsequently sintered in air at high temperatures to produce Co3O4 fibers.The results show that Co3O4 fibers faithfully retain the fibrous cotton morphological and microstructure features,and the cotton is completely removed when the sintering temperatures reaches 600℃.
