Metal@MOFs catalyst materials fabricated by solvated metal atom dispersion (SMAD) approach

该项目的主要目标是利用以下两种方法在骨架材料、金属有机骨架(MOF)或共价有机骨架(COF)的孔内引入高活性的超小金属和金属合金团簇a)溶剂化金属原子浸渍法(SMAI)：可以通过使用溶剂化金属原子分散(SMAD)方法将原位生成的溶剂化金属原子捕获到骨架孔内来实现。B)种子和生长方法(SAGA)：可以通过在SMAD合成的胶体金属纳米颗粒周围生长MOF来实现。SMAD方法用于SMAI和SAGA的一般性允许在多孔性框架内纳入广泛的团簇(金属包括主族、过渡金属和稀土、合金和半导体)。该项目的主要目标是评估两种金属-MOF材料制备方法，包括目标材料的微观结构表征。长期的前景是将这两种方法结合起来，获得金属-MOF和金属-COF杂化材料，并为制备广泛应用的纳米催化剂开发新的概念。我们将主要关注MOF，但我们也将评估COFS的SMAI。

The primary goal of the project is to incorporate highly active ultra-small metal and metal alloy clusters inside the pores of framework materials, metal organic frameworks (MOFs) or covalent organic frameworks (COFs), using the following two approachesa) Solvated metal atom impregnation approach (SMAI): can be achieved by judicious trapping of in-situ generated solvated metal atoms inside pores of frameworks using solvated metal atom dispersion (SMAD) method. b) Seed and growth approach (SAGA): can be achieved by growing MOFs around SMAD synthesized colloidal metal nanoparticles.The generality of the SMAD method for SMAI and SAGA allows incorporation of a wide range of clusters (metals including main group, transition, and rare earth, alloys and semiconductors) inside porous frameworks.The primary goal of the project is the evaluation of the two approaches for metal-MOF materials fabrication including microstructure characterization of the target materials. The long term perspective is to combine these two approaches to obtain metal-MOF and metal-COF hybrid materials and develop new concepts for fabrication of nano catalysts for a wide variety of applications. We will primarily focus on MOFs, however, we will evaluate SMAI for COFs, too.
