“…The isothermal curve of the immobilized enzyme and blank sample showed that, after the CALB was added to the sol–gel, the hysteresis loop disappeared in the immobilized enzyme particles. This is because the pores in SiO 2 were filled with CALB …”

Enzymatic processes coupled with continuous microfluidic techniques have significant application prospects in pharmaceuticals and fine chemicals. It is important to stably load enzymes in microreactors. This study reported a sol−gel method for preparing wall-coated immobilized enzyme microreactors (W-IMERs) by entrapment of Candida antarctica lipase B (CALB). The W-IMERs were simply constructed in one step by a flow coating process in a capillary. Compared with the free enzyme, the tolerance of immobilized enzyme to ethanol and temperature is significantly improved, and the yield of immobilized enzyme activity is 76.12% in the batch reactor. In W-IMERs, the yield of immobilized enzyme activity increased to 82.95%. The W-IMERs maintained stable activity in 10 cycles for up to 30 days. A CFD model was also established to explore the relationship between the internal reaction and the mass transfer in W-IMERs. The relationship between the internal and external diffusion limits of W-IMERs and the overall reaction rate was analyzed by dimensionless numbers. The results indicated that sol−gel flow coating is a simple and effective method for the preparation of enzymatic microreactors. An in-depth understanding of the relationship between diffusion limitation and reaction rate will have a significant impact on the overall performance of enzyme-catalyzed microreactors.

“…An FDCA yield of about 42% was obtained (Table , entry 23) . Recently, silica-based supporters including cyclodextrin-templated and amino-functionalized mesoporous silica were designed and prepared to covalently immobilize CAL-B for the production of FDCA from DFF by two groups. , Although the initial activities of these immobilized enzymes were good, their operational stability seemed to be unsatisfactory, as the catalytic activities substantially reduced after five recycles.…”

Biobased furans, such as furfural, 5-hydroxymethylfurfural, and 2,5-furandicarboxylic acid, are recognized as the top-value platform chemicals in the valorization of biomass to chemicals, fuels, and materials. Biocatalysis has emerged as a promising technique in the chemical and pharmaceutical industries because of exquisite selectivity, mild reaction conditions, environmental friendliness, etc. In this comprehensive review, we summarize the recent advances in (chemo)biocatalytic conversion of biobased furans, based on the reaction types including oxidation, reduction, C–C and C–N bonds formation, esterification, and amidation. Particularly, the biocatalysts and their catalytic mechanisms/pathways are critically discussed to allow the rational design and construction of efficient enzymes/multienzyme systems/chemobiocatalytic systems. Besides, various biocatalyst engineering and reaction engineering strategies are highlighted to intensify the processes. Future research directions are proposed to expand the chemical space of furans as well as to improve the commercial acceptance of biocatalytic processes.

“…In this approach, the RaMeβCD had a two-fold role, i.e. it showed a pore expansion effect on the γ-Al2O3 shell covering SnO microcrystals [53,54] and at the same time,it acted as structure directing agent owing to its surface-active properties [43,55] which are beneficial for reducing the surface energy of SnO microcrystals, thus facilitating their co-assembly with g-Al2O3nanoparticles.…”
