Final Report Summary - MULTIMOF (Preparation of multi-functional metal organic framework catalysts)
Highlighting significant results
(1) Preparation of basic
(1.1) Basic catalysts display a good catalytic performance in Knoevenagel condensation reactions
(1.2) The prepared materials were also tested on separation of CO2 / CH4, holding promises for the purification of natural gas.
(2) Preparation of acid catalysts
Three different procedures have been followed for the preparation of acid catalysts: One based on the encapsulation of polyoxymethylene (POM) in metal-organic frameworks (MOFs), the second one based on post modification of MOFs to introduce sulfoxy groups, and third one based on the controlled generation of acid defects that lead high catalytic activity in acid catalysed reactions and proton conductivity.
(3) Preparation of metal acid catalysts
Pt supported on MOF containing phosphotungstic acid was prepared and it was tested in CO oxidation and preferential oxidation (PROX) reaction. These results demonstrated that POM-MOF composites offer excellent possibilities for nanoparticle engineering.
(4) Preparation of acid-base catalysts
It was found that POMs could be easily immobilised an amino framework. The characterisation demonstrated that the antagonist functionalities (polyoxometalates and amino groups) are present in the framework.
(5) Preparation of MOFs monolith
The first MOF supported monolith has been prepared and used in oxidation reactions. The MOF monolith was applied in the selective oxidation of tetralin.
(6) Chloromethylation
A universal method for post-synthetic modification of MOFs was developed through the decoration of the MOF with chloromethyl groups that can be easy replaced by every group of choice.
