The encapsulation of metal nanoparticles (MNPs) inside porous organic hosts (POHs), such as metal-organic frameworks, covalent organic frameworks, organic molecular cages, and amorphous porous organic polymers has attracted significant attention because this procedure can generate highly catalytically active MNPs. This short review describes important recent progress in the fabrication of active MNP catalysts through confinement inside POH cavities, including various innovative synthetic strategies and catalytic applications. In particular, several representative reports of [email protected] hybrids are chosen to showcase why such POHs are so unique for confining MNPs and why the confined MNPs possess superior catalytic activity, selectivity, and stability. Finally, the challenges of employing [email protected] catalysts for future practical catalytic applications are addressed.

金属纳米颗粒（MNP）在多孔有机主体（POH）中的封装，例如金属有机骨架，共价有机骨架，有机分子笼和无定形多孔有机聚合物，已经引起了广泛的关注，因为此过程可以生成高度催化活性的MNP。这篇简短的评论介绍了通过限制POH腔内制造活性MNP催化剂的最新重要进展，包括各种创新的合成策略和催化应用。特别是，选择了[电子邮件保护的]杂种的几篇代表性报道来展示为什么这种POH对于限制MNP如此独特，以及为什么限制的MNP具有优异的催化活性，选择性和稳定性。最后，
