Vectorial Catalysis in Surface‐Anchored Nanometer‐Sized Metal–Organic Frameworks‐Based Microfluidic Devices

Abstract: Vectorial catalysis—controlling multi‐step reactions in a programmed sequence and by defined spatial localization in a microscale device—is an enticing goal in bio‐inspired catalysis research. However, translating concepts from natural cascade biocatalysis into artificial hierarchical chemical systems remains a challenge. Herein, we demonstrate integration of two different surface‐anchored nanometer‐sized metal–organic frameworks (MOFs) in a microfluidic device for modelling vectorial catalysis. Catalyst immob… Show more

“…When the enzymes have different optimal functioning conditions, one can consider the approach of immobilizing the enzymes on different particles and place the particles in separate compartments along the flow pathway, so that one can maximize the enzyme activity and extend the lifetime of the multi-enzymatic system. 20 Supplementary information includes methods of protein expression and purification, details of enzymatic activity assays, details of optimization of concentration of Mg 2+ and amount of hydrogel particles in the enzymatic reaction, Figure S1 to S3, Table S1 and S2.…”

“…Recent emerging use of MOFs is in the area of heterogeneous catalysis. One of the goals in heterogeneous catalysis is to make the reactions proceed greener by combining different reagents to give a single product, preferably under mild reaction conditions. This would enhance the atom economy and the reactions would also be green. , …”

“…Continuous and high-yield separation has been an important but challenging process, especially in coupling with microreactors. Microreactors have been developed for a wide range of applications, but further development of microseparators is needed to obtain target products in a continuous fashion. Miniaturization of separators is essential owing to the enhanced surface area and reduced diffusion distance . At present, membrane-based extraction in microseparators is mostly the membrane separation after biphasic mixing, the shortcomings of which include solvent loss, emulsion formation, ease of flooding, etc. Moreover, the mass transfer efficiency diminishes as the solvent-to-feed ratio becomes much less than one and multiple stages are typically required to achieve high-yield separation since the effectiveness of each stage is limited by equilibrium. , …”
