Controllable integration of metal-organic framework (MOF) and noble metal nanoparticles is attractive for diverse applications, including but not limited to catalysis, sensing, theragnostics and plasmonic devices. Extensive research efforts have been implemented to prepare noble metal encapsulated into or deposited onto transition metal MOFs, especially Zn-based MOFs. However, few or none research has been conducted to incorporate noble metal (e.g., gold) nanoparticles with lanthanide-based MOFs. Gadolinium, lying in the middle of the lanthanide elements family, was herein chosen as a model due to its known advantages for a variety of applications (e.g., contrast agents for magnetic resonance imaging). In this work, the methods for synthesizing gold core-gadolinium MOF shell at both room temperature and elevated temperature will be discussed. Understanding how gadolinium acts differently from transition metals during the synthesis will also be addressed. Finally, it is anticipated that the controllable synthesis can provide high quality materials for diverse applications.
