Recent highlights of our research include the joint study with the groups of Tom Vosch and Sebastian Kunz concerning the influence of light on the particle formation in a colloidal synthesis of Pt Nanoparticles.
The basic finding was that in a standard polyol synthesis performed at room temperature, the exposure to light is crucial for the particle formation process. This lead to the idea to use UV light to actively influence particle formation, an exciting new synthesis strategy for unprotected nanoparticles, which is currently under investigation.
Work from founded by project was selected Danish Research Result of See link: www. We employ IL-TEM in combination with accelerated stress tests to investigate the degradation mechanisms of model catalysts as well as carbon supported high surface area catalysts. The aim is to understand how the different degradation channels depend on the treatment conditions and the catalyst support.
This knowledge is then utilized for the development of improved catalysts. Speder, A. Zana, I. Spanos, J. Kirkensgaard, K. Mortensen, M. Hanzlik, M.

Principle of Catalysis 3. Normally catalyst surface must have the high active energy, right structure, and enough spaces. Industrial Applications 1. Conclusions 1. Nanomaterials offer many possibilities as catalysts to meet future demands in catalytic process technology in petroleum refining, petrochemical industry, and synthetic fuels production of the future.
The higher activity and better selectivity of nanocatalysts over traditional catalysts are attributed to their large specific surface area, high percentage of surface atoms and special crystal structures. The development of nanocatalysts is increasingly supported by advances in preparation, characterization and testing of catalysts. References 1. Jafapour, M.
