Reactions within the confined spaces of a microreactor often yield higher conversion and better selectivity as a result of enhanced transport processes. Traditional microfluidic reactors often constrain the fluid flow within fabricated microchannels leading to a large pressure gradient. This work employs the network of interconnecting channels defined by the strands of glass fibers in a glass fiber membrane as conduits for fluid flow, with the glass fibers as support for the MOF catalysts. Thus, a microreactor with a low pressure drop was obtained despite the narrow width of the flow channels (< 100 µm). The large contact surface (i.e., 200,000 m²/m³) is ideal for catalyst deposition and ZIF-8 for Knoevenagel condensation reaction, PdZIF-8 for selective hydrogenation reaction and FeBDC for acetalization reaction were successfully prepared. A new synthesis approach enables each strand of glass fibers to be completely cladded with an intergrown layer of MOF catalysts ensuring good adhesion and catalyst stability. Indeed, these MOF catalysts display higher yield and better stability compared to MOF catalyst powder in batch reactor and fixed-bed microreactor.

由于运输过程的增强，微反应器密闭空间内的反应通常会产生更高的转化率和更好的选择性。传统的微流体反应器通常将流体流约束在制造的微通道内，从而导致较大的压力梯度。这项工作采用了由玻璃纤维膜中的玻璃纤维束所定义的互连通道网络作为流体流动的管道，而玻璃纤维则作为MOF催化剂的载体。因此，尽管流道的宽度较窄（＜100μm），仍获得了具有低压降的微反应器。较大的接触面积（即200,000 m ² / m ³）是催化剂沉积的理想选择，ZIF-8用于Knoevenagel缩合反应，PdZIF-8用于选择性加氢反应，FeBDC用于缩醛化反应已成功制备。一种新的合成方法使每根玻璃纤维都可以完全包覆一层MOF催化剂，从而确保良好的附着力和催化剂稳定性。实际上，与间歇式反应器和固定床微反应器中的MOF催化剂粉末相比，这些MOF催化剂显示出更高的产率和更好的稳定性。
