通过NH2-MCM-41与水杨醛反应得到席夫碱配体，然后加入八水氧氯化锆形成络合物，制得Zr(IV)-salen-MCM-41催化剂。采用X射线衍射、N2吸附-脱附、热重、红外光谱、电感耦合等离子体发射光谱和能量散射谱等分析手段对催化剂结构进行了表征。在含有该催化剂的体系中进行了硫化物选择氧化为亚砜以及醛与丙二腈和氰乙酸乙酯的Knoveonagel缩合反应，并考察了催化剂的循环使用性能。
Zr(IV)‐salen‐MCM‐41 was prepared by reaction of NH2‐MCM‐41 with salicylaldehyde to afford Schiff base ligands. Thereafter, ZrOCl2·8H2O was reacted with the Schiff base ligands for complex formation. The structural properties of the synthesized materials were investigated by a number of analytical techniques including X‐ray diffraction, N2 sorption‐desorption, thermogravimetric analy‐sis, Fourier transform infrared spectroscopy, inductively coupled plasma atomic emission spec‐troscpopy, and energy dispersive X‐ray spectroscopy. Catalytic studies of the mesoporous materials functionalized with Zr(IV)‐Schiff base complexes were investigated and extended to selective oxida‐tion of sulfides to sulfoxides and the Knoevenagel condensation reactions of aldehydes with malo‐nonitriles and ethyl cyanoacetate. Additionally, catalyst recycling of the Zr‐salen‐MCM‐41 materials was also studied.
