“…The results indicated that the segment flow microreactor allowed the fast synthesis (10 min) of ZIF-8 crystals with a narrow PSD, but the largest total flow rate was just 1.0 mL/min. Wu et al 35 adopted a continuous droplet microreactor to accelerate the generation of ZIF-8 and MIL-100, and the results indicated that the microreactor method could achieve crystallinity comparable to that using the traditional batch hydrothermal method while significantly reducing the residence time from 200 min to 24 s. However, the total flow rate was just 0.53 mL/min. In summary, the low throughput hindered the industrial applications of the ordered microreactors.…”

The relationship between the flow pattern evolution and performance of oscillating feedback microreactors (OFMs) for the synthesis of ZIF-67 nanoparticles was investigated by a photomicrography technique. Accordingly, an oscillating feedback microreactor (OFM) with an optimized structure was identified for high-throughput ZIF-67 production. By varying the experimental conditions (i.e., flow rate, aging time, precursor concentration [Co 2+ ], solvent, and cobalt source), the average size of ZIF-67 products can be adjusted (from 16 to 294 nm) with narrow particle size distribution (geometric standard deviation: 1.08−1.14) as well as with controllable morphology (sphere or rhombic dodecahedron). The maximum total flow rate can reach 160 mL/min, indicating that a highthroughput synthesis of ZIF-67 is achieved. The screening method can be extended to optimize other microreactors, and the resulting OFMs can be applied to produce other kinds of nanoparticles.

“…The microfluidic-based method is a cost-effective green process, [37] having favorable characteristics such as good mass and heat transfer effects, speeding up the growth rate of MOF in droplets, and reduced energy consumption and solvent usage. [38][39][40] Through the precise control of different reaction conditions, MOF with narrow size distribution and specific types can be synthesized, thereby achieving good reproducibility and production stability. [41][42] Among the microfluidic-based approach, continuous flow synthesis of the micro-droplet reaction system can quickly realize the efficiency of heat transfer and mass transfer in the droplet, improve the sensitivity of the product to the reaction parameters, and significantly reduce the use of precursor solutions.…”

A new and efficient technique is developed by combining the hyphenated microfluidic‐ and aerosol‐based synthesis with the coupled differential mobility analysis for the effective and continuous synthesis and simultaneous analysis of metal–organic frameworks (MOFs)‐derived hybrid nanostructured products. HKUST‐1, a copper‐based MOF, is chosen as the representative to fabricate Cu‐based hybrid catalysts for reverse water‐gas shift (RWGS) reaction, an effective route for CO2 utilization. The effect of precursor concentration and carrier selection on the properties of the resulting products, including mobility size distribution, crystallization degree, surface area, and metal dispersion are investigated, as well as the correlation between the material properties of the synthesized catalysts and their catalytic performance in RWGS reaction in terms of conversion ratio/rate, selectivity, and operational stability. The results indicate that the continuous microfluidic droplet system can successfully synthesize MOF colloids, followed by the continuous production of MOF‐derived hybrid materials through the tandem aerosol spray‐drying‐reaction system. High catalytic activity and low initiate temperature toward RWGS (turnover frequency = 0.0074 s−1; 450 °C) are achievable. The work facilitates the production and the designed concept of relevant MOF‐derived hybrid nanostructured catalysts in the continuous synthesis system and the enhancement of applications in CO2 capture and utilization.
