Novel synthesis routes towards improved catalyst stability

Many industrial processes like Fe supported Fischer-Tropsch and Cu supported Methanol synthesis suffer from the catalyst active site deactivation, often caused by sintering and ripening of the metal nanoparticles [1]. By evaluating the metal-organic framework structure, and specifically their metal nodes, synthesis routes towards both properly spaced and sized active sites can be obtained. 

The first goal in this project is to characterize the obtained metal nanoparticles and their supports by methods such as electron microscopy, X-ray diffraction and adsorption spectroscopy, and physisorption and chemisorption. Subsequently, the samples are subjected to catalytic testing. By assessing these structure-performance characteristics, synthesis routes are adjusted towards improvement of the stability and activity.
