Recent Progresses in Metal–Organic Frameworks Based Core–shell Composites
Résumé
Encapsulation of active guest compounds inside Metal-Organic Frameworks (MOFs) architectures is one of the most promising routes to reach properties beyond those of the bare MOFs and/or guest species. In contrast with the conventional host/guest composites that rely on the encapsulation of guest species into MOF cavities, core-shell composites display a better accessibility to the pores ensuring an optimal diffusion of the substrate while presenting a unique structure that prevents from the aggregation and the runoff of the active guests and ensures a tight interaction between core and shell, leading to synergistic effects. Herein, this progress report summarizes the recent advances in this field. The main synthetic strategies are first discussed before highlighting few potential applications, such as heterogeneous environmental catalysis, gas separation and sensing, while others (bio-applications…) will be briefly mentioned. We conclude this review by a critical perspective in order to promote new generations of MOFs based composites for energy-related applications.
