Metal-organic framework (MOF) nanoparticles, also called porous coordination polymers, are a major part of nanomaterials science, and their role in catalysis is becoming central. The extraordinary variability and richness of their structures afford engineering synergies between the metal nodes, functional linkers, encapsulated substrates, or nanoparticles for multiple and selective heterogeneous interactions and activations in these MOF-based nanocatalysts. Pyrolysis of MOF-nanoparticle composites forms highly porous N- or P-doped graphitized MOF-derived nanomaterials that are increasingly used as efficient catalysts especially in electro- and photocatalysis. This review first briefly summarizes this background of MOF nanoparticle catalysis and then comprehensively reviews the fast-growing literature reported during the last years. The major parts are catalysis of organic and molecular reactions, electrocatalysis, photocatalysis, and views of prospects. Major challenges of our society are addressed using these well-defined heterogeneous catalysts in the fields of synthesis, energy, and environment. In spite of the many achievements, enormous progress is still necessary to improve our understanding of the processes involved beyond the proof-of-concept, particularly for selective methane oxidation, hydrogen production, water splitting, CO reduction to methanol, nitrogen fixation, and water depollution.
金属有机框架(MOF)纳米颗粒,也被称为多孔配位聚合物,是纳米材料科学的重要组成部分,并且它们在催化中的作用正变得至关重要。其结构的非凡多样性和丰富性为金属节点、功能连接体、封装的底物或纳米颗粒之间提供了工程协同效应,以实现这些基于MOF的纳米催化剂中的多种选择性非均相相互作用和活化。MOF纳米颗粒复合材料的热解形成了高度多孔的N或P掺杂石墨化MOF衍生纳米材料,这些材料越来越多地用作高效催化剂,尤其是在电催化和光催化中。本文首先简要总结了MOF纳米颗粒催化的这一背景,然后全面回顾了过去几年快速增长的相关文献。主要部分包括有机和分子反应催化、电催化、光催化以及前景展望。利用这些定义明确的非均相催化剂,在合成、能源和环境领域应对了我们社会面临的重大挑战。尽管取得了许多成就,但仍有必要取得巨大进展,以加深我们对概念验证之外所涉及过程的理解,特别是对于选择性甲烷氧化、制氢、水分解、将CO还原为甲醇、固氮和水污染治理。
