采用新方法合成了nio - sio2溶胶柱状蒙脱土。正硅酸四乙酯（TEOS）和六水硝酸镍（Ni(NO3)2·6H2O）与辛胺同时嵌入h -蒙脱土中间层。辛胺催化TEOS层间水解得到硅氧烷柱状蒙脱土。在550℃脱除有机化合物后，得到了一种新的nio - sio2溶胶柱状蒙脱土。柱状样品的氮吸附-解吸等温线表明，在硅酸盐层之间形成了大量的微孔和介孔，使柱状样品的表面积达到554 m2/g，总孔隙率为0.626 ml/g。考察了ni - sio2溶胶柱型蒙脱土在苯加氢反应中的催化活性。
NiO-SiO2-sol pillared montmorillonite was synthesized using a novel method. Tetraethyl orthosilicate (TEOS) and hexahydrate nickel nitrate (Ni(NO3)2 · 6H2O) were intercalated into the interlayers of H-montmorillonite simultaneously with the intercalation of octylamine. Interlamellar hydrolysis of TEOS catalyzed by octylamine resulted in the siloxane-pillared montmorillonite. A new NiO-SiO2-sol pillared montmorillonite was obtained after removing the organic compounds at 550°C. The nitrogen adsorption-desorption isotherm for the pillared sample revealed that a large number of micro- and mesopores were created between the silicate layers, giving rise to a large surface of 554 m2/g and total porosity of 0.626 ml/g. The catalytic activity of the NiO-SiO2-sol pillared montmorillonite was evaluated in hydrogenation of benzene.
