Evaluating the catalytic influence of metal sites on derivates obtained from the calcination of metal–organic frameworks (MOFs) is very important for the rational construction of novel MOFs. Based on this catalytic functional guidance, two new Co-MOF and CoNi-MOF crystals were designed and synthesized, and further pyrolyzed to obtain corresponding porous carbon-based catalysts. Interestingly, the derivates exhibited better catalytic performance toward the tandem reaction of dehydrogenation of NH3BH3 and subsequent hydrogenation reduction of nitro/olefin compounds than those of the CoNi-ZIF (a star MOF)-derived CoNi@carbon and most metal catalysts. Significantly, the CoNi@C maintained excellent activity, even after 30 cycles, demonstrating its great longevity and durability, which are especially important for the practical application of metal catalysts in industrial catalysis.

新型CoNi-金属-有机骨架晶体衍生的CoNi @ C:合成和有效的级联催化。

评估金属位点对由金属-有机骨架(MOFs)煅烧获得的衍生物的催化影响,对于合理构造新型MOFs非常重要。基于该催化功能指导,设计并合成了两种新的Co-MOF和CoNi-MOF晶体,然后进一步热解以获得相应的多孔碳基催化剂。有趣的是,这些衍生物对NH 3 BH 3的脱氢串联反应表现出更好的催化性能。以及随后的硝基/烯烃化合物的氢化还原,要比CoNi-ZIF(星形MOF)衍生的CoNi @碳和大多数金属催化剂的氢化还原。值得注意的是,即使在30次循环后,CoNi @ C仍保持出色的活性,这表明它具有很高的寿命和耐用性,这对于金属催化剂在工业催化中的实际应用特别重要。
