Abstract

We are investigating a number of different interesting carbon nanostructures modified by substitutional defects, metal nanoparticles and transition metal oxide nanoparticles. The aim with our projects is to understand the stability and formation of these defects, the interaction of the carbon nanostructures with the metal nanoparticles and the performance of these materials for catalytic reaction such as water splitting, oxygen reduction reactions and alcohol oxidation in fuel cells. Our last application was granted with six months project time only. We would be very happy if the project time could be granted for 12 months to allow for longer planning of our projects. In the last six months we have carried out a number of successful studies of fascinating hybrid materials, and we have published the following scientific papers using the HP2CN infrastructure. In all of them we have acknowledged HP2CN for support 1. Joakim Ekspong, Tiva Sharifi, Andrey Shchukarev, Alexey Klechikov, Thomas Wågberg, Eduardo Gracia‐Espino.
