提出了一种通过水解预锚定酰胺在二氧化硅上产生相邻羧基和氨基的酸碱对位点的方法。这种方法可以产生一个相邻的酸碱对位点。该催化剂在4-硝基苯甲醛与丙酮的醛缩反应中表现出优异的催化性能，优于仅含氨基的催化剂和传统制备的酸碱催化剂。
A method to create adjacent acid-base pair sites, which are carboxyl and amino groups, respectively, on silica through hydrolysis of pre-anchored amide is proposed. This method can produce an adjacent acid-base pair site. The catalyst showed excellent catalytic performance for aldol condensation of 4-nitrobenzaldehyde with acetone, overwhelming the catalyst having only amino group and an acid-base catalyst prepared in a conventional manner.
