A 3D nanoweb-like zeolite imidazole framework (ZIF-8) as an efficient heterogeneous catalyst was structured inside a functionalized microfluidic channel by immobilizing the ZIF on 3D carbon nanotube (CNT) networks across the gap among the built-in micropillars for the Knoevenagel condensation reaction. The quantitative conversion was achieved under mild conditions of ethanol solvent and room temperature. The ZIF-8 3D nanoweb systems showed higher conversion than the identical systems without CNT-based networks which indicates the catalytic superiority of 3D nanoweb structures.

3D纳米网状沸石咪唑骨架在微流体系统中的催化应用

通过将ZIF固定在3D碳纳米管（CNT）网络上跨越内置微柱之间的缝隙进行Knoevenagel缩合的3D纳米网状沸石咪唑骨架（ZIF-8）作为有效的非均相催化剂反应。在温和的乙醇溶剂和室温条件下实现了定量转化。与没有基于CNT的网络的相同系统相比，ZIF-8 3D纳米纤维网系统显示出更高的转化率，这表明3D纳米纤维网结构具有催化优势。
