本文利用柳絮的微米管结构，通过碳化制备了碳微米管，并用扫描电子显微镜（SEM）和红外光谱（FTIR）对碳微米结构进行了表征。还以碳微米管作为催化剂载体，研究其对甘油和乙酸的酯化反应的选择性。“,”In this study,catkin micro-structure was used as a template to obtain the carbon microtubes by carbonization technology.The structure of carbon microtubes was characterized with Scanning Electron Microscope(SEM)and FTIR.The catalytic activity of the carbon microtubes was studied by esterification of glycerol with acetic acid.
