Abstract:
A report is given on the recent advances in the design, synthesis, and development of a new catalytic microreactor for the selective and continuous synthesis of value-added substances used in fine organic synthesis and pharmaceutical industry. Inside this advanced reactor, metal nanoparticles are incorporated into mesoporous materials that are deposited as very active and selective catalytic films on the walls of capillary microchannels with diameters of 220 and 530 µm. These microreactor systems require no subsequent separation of the catalyst, which allows their continuous operation. Crystalline and amorphous metal oxides based on titanium dioxide synthesized using the sol gel technique and containing catalytically active polymetallic nanoparticles are potentially the most stable coatings. The catalytic properties and operational stability of capillary microreactors are studied at atmospheric pressure and compared to those of conventional industrial batch reactors. Our Pd50Zn50/TiO2 coating displays higher activity (1.5 gMBE/(gPd s)) and selectivity (96.7%) than coatings described earlier, and retains high catalytic performance after 88 h of a reaction with Lindlar’s industrial catalyst. © 2021, Pleiades Publishing, Ltd.
