The invention discloses a zirconium-based MOF catalyst loaded with double active sites as well as a preparation method and an application of the zirconium-based MOF catalyst. The method comprises thefollowing steps: adding zirconium salt and an organic ligand into an organic solvent, taking organic acid as a regulator, and carrying out self-assembly reaction to obtain a metal organic framework; adding salicylaldehyde for aldehyde amine condensation to obtain chelating coordination sites, adding palladium salt, and performing coordination through an impregnation method; reducing the obtained MOF in hydrogen to obtain an MOF loaded with Pd nanoparticles; reacting MOF and zinc salt in an organic solvent, and obtaining the catalyst. The Pd-Zn-coated UiO-68-NH2-CH3 catalyst synthesized by thepreparation method disclosed by the invention has efficient catalytic activity in a tandem alcohol oxidation/aldehyde cyanosilylation reaction. According to the catalyst, a metal organic framework UiO-68-NH2-CH3 is constructed, Pd nanoparticles and Zn are loaded by taking the metal organic framework UiO-68-NH2-CH3 as a carrier, the loading capacity of the Pd nanoparticles is 4-8wt%, and the loading capacity of the Zn is 3-5wt%.

Cyanosilylation of carbonyl compounds provides protected cyanohydrins, which can be converted into many kinds of compounds such as amino alcohols, amides, esters, and carboxylic acids. In particular, the use of trimethylsilyl cyanide as the sole carbon source can avoid the need for more toxic inorganic cyanides. In this paper, we describe an electrochemically initiated cyanosilylation of carbonyl compounds and its application to a microflow reactor. Furthermore, to identify suitable reaction conditions, which reflect considerations beyond simply a high yield, we demonstrate machine learning-assisted optimization. Machine learning can be used to adjust the current and flow rate at the same time and identify the conditions needed to achieve the best productivity.
