Results in brief
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.

Project objective
The overall aim of this project is to engineer new mono and multifunctional nanostructured solids to be used as catalyst for multi-step, one-pot reactions. The key objectives are: 1. Create stable nano-structured super basic catalysts based on Metal Organic Frameworks (MOFs) by using synthetic and/or post-synthetic approaches. 2. Create nano-structured solids containing covalently bonded sulphonic groups by using synthetic and/or post synthetic methods. 3. Create acid MOFs with metal nanoparticles encapsulated in the MOF cavities (acid-metallic catalyst). 4. Produce acid-base MOFs by using synthetic and/or post synthetic approaches. The main motivations for the exploration and development of efficient catalysts are to conserve energy, to produce fine chemicals and to develop environmentally friendly and safe technologies. Despite major improvements over the past few decades, many existing commercial catalysts are still plagued by low efficiency, high cost, and/or production of large quantities of hazardous wastes. Furthermore, many of them have been designed to catalyze a single reaction in multi-step reactions or to produce multiple products, in contrast to industry’s needs for efficient multi-step, one-pot catalytic processes. The tailoring of multifunctional catalysts is a big challenge for the research community and for the society in general, since proper catalysts may reduce the economical and environmental costs of crucial catalytic process. Multifunctionality in heterogeneous catalysis has been scarcely studied, with respect to multifunctional solids, the heterogeneous catalysis toolbox is still empty. In this sense MOFs are called to play an important role in the near future due to their wide chemical versatility and modifiability. The emphasis and final target of this proposal is to design and to apply MOFs as bi-functional catalysts. The main part of the proposed project, will be carried out at the Delft University of Technology, abbreviated as TU
