Metal-organic frameworks (MOFs) are a versatile class of porous coordination materials that have found widespread application in various fields, particularly as heterogeneous catalysts. Due to the modular nature and molecular tunability of the metal node-linker coordination in MOFs, they are considered competent hosts for secondary materials in their extensive pore channels. Modifications of the metal nodes or ligand functionalisation in MOFs can improve the anchoring ability of nanoparticles, effectively enhance the nanoparticles' stability, and mitigate the inherent nature of nanoparticles to aggregate. In this review, the synthetic strategies ("ship-in bottle", "bottle-around-ship", and one-pot) and novel characterisation techniques of nanoparticle-MOF (NP-MOF) composites are discussed in detail. The precise determination of nanoparticle-MOF coordination is crucial to shed light on the structure-activity relationships of the catalytic composites. Recognising the synergistic properties of MOFs and metallic nanoparticles, we also explore recent advancements in NP-MOF composites with a special focus on zirconium-based MOFs for catalytic applications within the last five years. Therefore, we aim to aid the reader in evaluating the up-to-date and state-of-the-art advancements concerning the chemistry of nanoparticles and MOFs as catalysts, acting as a path for future learning and optimisations.
金属有机框架材料（MOFs）是一类用途广泛的多孔配位材料，已在各个领域得到广泛应用，尤其是作为多相催化剂。由于MOFs中金属节点 - 连接体配位的模块化性质和分子可调节性，它们被认为是其广阔孔道中二次材料的理想宿主。MOFs中金属节点的修饰或配体功能化可以提高纳米颗粒的锚定能力，有效增强纳米颗粒的稳定性，并减轻纳米颗粒聚集的固有特性。在这篇综述中，详细讨论了纳米颗粒 - MOF（NP - MOF）复合材料的合成策略（“瓶中造船”、“船围瓶”和一锅法）以及新型表征技术。精确确定纳米颗粒与MOF的配位对于阐明催化复合材料的结构 - 活性关系至关重要。认识到MOFs和金属纳米颗粒的协同特性，我们还探讨了NP - MOF复合材料的最新进展，特别关注过去五年中用于催化应用的锆基金属有机框架材料。因此，我们旨在帮助读者评估关于纳米颗粒和MOFs作为催化剂的化学领域的最新和最先进进展，为未来的学习和优化提供途径。
