以天然层状黏土蒙脱石(MMT)为前体,通过液相沉积-沉淀将镍物种引入水溶液中剥离为MMT纳米片表面的简易方法制得Ni/MMT纳米片.该Ni/MMT纳米片由于是二维(2D)结构,利于芳烃及其加氢产物的传质扩散,相比Ni/SBA-15和Ni/γ-Al2O3催化剂,具有更为高效的芳烃加氢性能,且在镍负载量高达18.5％时,其四氢萘加氢的转化频率(TOF)达到最高值.
Nanosheets of Ni/Clay as high efficient catalysts for hydrogenation of aromatics
Using montmorillonite (MMT),a natural layered clay,as the layered precursor,nanosheets of Ni/MMT are obtained via a facile method,in which the nickel components are introduced on to the surface of the exfoliated MMT nanosheets dispersed in water via deposition-precipitation with nickel nitrate and urea.Due to their unique properties originated from the two-dimensional (2D) structure,which favors mass transfer and diffusion of the aromatics and their hydrogenation products over the catalyst during reaction,the obtained nanosheets of Ni/Clay show higher efficient for hydrogenation of aromatics than Ni/SBA-15 and Ni/γ-Al2O3 catalysts.And the highest TOF for hydrogenation of tetralin over the nanosheets of Ni/Clay is obtained as nickel loading being high to 18.5％.
