Metal nanoparticles, especially those composed of noble metals, are essential in various applications, such as catalysis, optics, and sensors. Achieving precise control over nanoparticle size, shape, and composition is crucial for enhancing their catalytic activity. One promising approach to achieve this is by using metal nanoclusters stabilized with ligands and encapsulating them into metal-organic frameworks (MOFs). MOFs provide a 3D, porous, and crystalline matrix that can effectively scaffold various species, including metal nanoclusters. This approach allows for the precise control of cluster size, composition, and spatial arrangement, which in turn affects the catalytic properties. The encapsulation process, however, is complex and involves interactions between the cluster and the MOF building blocks. Different clusters show varying degrees of stability during encapsulation, and the size of the cluster influences its distribution within the MOF. Understanding the cluster-MOF interactions and the encapsulation mechanism is crucial for designing efficient nanoscale catalysts and achieving better control over their properties.
