无机柱撑蒙脱石的柱化机理及应用研究进展

Advance in Studies on Pillaring Mechanism and Application of Inorganic Pillared Montmorillonite

柱撑蒙脱石作为一种新型的多孔材料是当前矿物材料学研究的热点之一,其具有大的比表面积、大小可调的孔径、强的酸性而成为性能优异的吸附剂和催化剂,在石油化工和环保领域具有广阔的应用前景.本文概述了柱撑蒙脱石的制备、柱化机理及其应用等方面的研究进展,指出了柱撑蒙脱石研究中存在的问题(热稳定性,水热稳定性和孔结构等),报道了柱撑蒙脱石研究热点,论述了柱撑蒙脱石研究的发展方向.

As a novel porous material, pillared montmorillonite（PILM） is one of hotspots for mineral material research. It use as an excellent adsorbent and catalyzer in petrochemical and environmental protection fields because of its greater surface - to - volume ratio, variable apertures and strong acid activity. The paper summarized the preparation of PILM, pillaring mechanism and utilization, pointed out some questions（ including thermal stability, and hydro - thermal stability, and pore structure） about PILM, and reported the hotspots of studies on PILM, and dissertated the study trend of PILM.
