3D monolithic reactor has shown great promise for varied heterogeneous catalysis reactions including water treatment, energy generation and storage, and clean fuel production. As a natural porous material, macroporous wood is regarded as an excellent support for inorganic catalyst due to its abundant polar functional groups and channels. On the other hand, a metal organic framework (MOF) has been widely used as heterogeneous catalyst due to its high specific surface area and large amount of microporosities. Combining macroporous wood and a microporous MOF is expected to produce a high-performance 3D reactor and is demonstrated here for Fischer–Tropsch synthesis. The carbonized MOF/wood reactor retains the original cellular structure with over 180 000 channels/cm2. When being decorated with hexagonal-shaped core–shell Co@C nanoparticles aggregates derived from Co-MOF, the MOF/wood reactor resembles a multi-cylinders reactor for Fischer–Tropsch synthesis. Because of the unique combination of macro- and microporous hierarchical structure, the 3D MOF/wood reactor demonstrates exceptional performance under high gas hourly space velocity (81.2% CO conversion and 48.5% C5+ selectivity at 50 L·h–1·gcat–1 GHSV). This validates that MOF/wood can serve as a multi-cylinders and high-power reactor for catalytic reactions, which is expected to be applicable for environmental and energy applications.

金属有机框架(MOF)/木材衍生的多缸大功率3D反应器

3D整体反应器已显示出巨大的前景,可用于各种非均相催化反应,包括水处理,能量产生和存储以及清洁燃料的生产。作为天然的多孔材料,大孔木材由于其丰富的极性官能团和通道而被认为是无机催化剂的极佳载体。另一方面,金属有机骨架(MOF)由于其高的比表面积和大量的微孔率而被广泛用作非均相催化剂。将大孔木材和微孔MOF结合使用有望产生高性能3D反应器,并已在此处进行了费托合成实验。碳化的MOF /木材反应器保留了超过180000个通道/ cm 2的原始孔结构。当用衍生自Co-MOF的六角形核壳Co @ C纳米粒子聚集体装饰时,MOF /木材反应器类似于费托合成的多圆柱反应器。由于大孔结构和微孔结构的独特结合,3D MOF /木材反应器在高气体时空速度下表现出了出色的性能(在50 L·h –1 ·g cat下, CO转化率为81.2%,C 5+选择性为48.5%)–1 GHSV)。这证实了MOF /木材可以用作催化反应的多缸和大功率反应器,有望应用于环境和能源应用。
