Supported Catalysis in Continuous-Flow Microreactors

This review surveys the recent developments to perform heterogeneous catalysis in continuous-flow microreactors. Three different types, namely, (i) packed-bed, (ii) monolithic, and (iii) wall-coated approaches are discussed to implement various kinds of catalysts in a microreactor. In addition, the applications of these supported catalysts to perform a variety of organic reactions are described. Furthermore, advantages of catalytic microreactors over classical batch reactors on one or more aspects of the reaction, such as rate, conversion, selectivity, and enantioselectivity are presented.
