| 摘 要： | 以钛酸四丁酯为原料,纳米纤丝化纤维素(NFC)为模板,制备NFC/TiO2气凝胶。采用扫描电子显微镜(SEM)、X射线衍射(XRD)、傅里叶变换红外光谱(FT-IR)、比表面积及孔径分析仪对其进行表征。结果表明:NFC/TiO2气凝胶中NFC保留了其原有的空间网络结构;TiO2主要以颗粒的形式附着在NFC表面;通过BET分析可知其比表面积为12.55 m2/g,平均孔径为17.07 nm。

| Abstract: | Nanofibrillated cellulose(NFC)/TiO2 aerogel was prepared with tetrabutyl titanate as raw material and NFC as template. NFC/TiO2 aerogel was characterized by scanning electron microscopy(SEM), X-ray diffraction(XRD), Fourier transform infrared(FT-IR) and specific surface area and pore size analyzer, respectively. The results showed that the original space network structure of NFC was kept in NFC/TiO2 aerogel.TiO2 mainly existed in the form of particles attached on the surface of cellulose nanofibrils.For NFC/TiO2 aerogel, the specific surface area was 12.55 m2/g and the average pore size was 17.07 nm analyzed by BET method. |
