PREPARATION AND CHARACTERIZATION OF POROUS CARBON PILLARED BENTONITE
摘要
Abstract
Porous carbon pillared bentonite was prepared from bentonite modified by C19H42BrN and C10H16CIN. The porous pillared bentonite were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray diffraction, nitrogen absorption/desorption, thermal-gravimetric analysis and differential scanning calorimetry. The influence of organic modifier on the characteristics of porous pillared bentonite was investigated. The results show that organic modifier combines with bentonite particles by covalent bond and ion embedding. The microstructure of porous carbon pillared bentonite looks like needle slice. The most probable pore size distribution is about 1.7 nm. The modifier slice mainly consists of two direction holes supported by a carbonization pillar. The high-temperature stability of carbon pillared bentonite was improved.关键词
