与传统醛亚胺缩合反应不同，选择含氮配体吡啶-2-甲醛作为醛基来源，以含有大量氨基官能团的NH 2-MIL-53（Al）为载体，过渡金属Cu 2+与含氮配体配位，制备了一种新型的、稳定性更好的MOFs催化剂Cu@Al-MIL-53-P21。该催化剂表现出交联的纳米棒形态。考察了催化剂的形貌对苯乙烯催化氧化活性的影响，结果表明，该催化剂不仅能促进苯甲醛的生成，而且能抑制苯甲酸和苯乙醛的生成。此外，本文还对最佳反应条件和反应机理进行了探讨.
Different from the traditional aldimine condensation reaction, N-containing ligand: pyridine-2-formaldehyde was selected as the source of aldehyde group, and NH2-MIL-53(Al) containing a large number of amino functional groups was took as the carrier, transition metal Cu2+ coordinated with N-containing ligand to prepare a new and more stable MOFs catalyst named Cu@Al-MIL-53-P21. The catalyst exhibited a cross-linked nanorod morphology. The effect of the morphology on the catalytic oxidation activity of styrene was studied, the results showed that the catalyst could not only promote the production of benzaldehyde, but also inhibit the production of benzoic acid and phenylacetaldehyde. In addition, the optimal reaction conditions and the reaction mechanism were also discussed in this paper.
