CoMn_2O_4纳米管的制备及表征

Preparation and characterization of CoMn_2O_4 nanotubes by sol-gel assisted electrospinning

利用溶胶凝胶-电纺法制备了CoMn2O4纳米材料,通过热分析(TG-DTA)、X射线衍射(XRD)、扫描电镜(SEM)等测试手段对所制备纳米纤维的组成、形貌结构、晶相结构等进行了分析和表征.结果表明,煅烧温度600℃时得到具有中空管状结构的CoMn2O4纳米材料,其平均晶粒尺寸为18.8nm.

CoMn2O4nanotubes was successfully synthesized by a sol-gel assisted electrospinning method followed by calcination at 600℃in air.These nanotubes were characterized for the morphological structural by thermal analysis（TG-DTA）,X-ray diffraction（XRD）,scanning electronmicroscopy（SEM）.The results show that the nanofibers have hollow nanostructure.The crystallite dimension is 18.8nm.
