SYNTHESIS OF POROUS MOF/COF DERIVED/BASED MATERIALS AND THEIR APPLICATIONS IN CATALYSIS

Abstract

In this work, we are aiming to develop some general approaches to synthesize multifunctional covalent organic framework (COF)/MOF-based nanostructures. For example, MOF nanoparticles can be grown in situ on nanotubes of copper silicate and other low-cost transition metal silicates. Besides, hierarchically porous metal oxides can be fabricated inside a mesoporous silica shell through confined transformation using MOF as a solid precursor. The resultant nanoreactors can be further loaded with different active metals for CO2 conversion to methanol, CO and CH4 which is resistant to sintering effect. Meanwhile, new approaches have been developed to synthesize unique COF structures, like the NPs@COF and hollow COF nanostructures. Formation mechanisms of all the above structures have been investigated and related applications have been explored.
