On the way towards more accurate understanding of the dynamics under gas atmosphere, Ernst Ruska-Center for Microscopy and Spectroscopy with Electrons has launched a Master Student Project that will deal with the challenges of beam effects on catalyst nanoparticles under gas environment. More specifically, in this project a systematic study on the effect of electron dose on the DENSsolutions Climate Nano-Reactor will be carried out as well as on the catalyst nanoparticles, with the aim of determining the optimum dose level in the trade-off between damage and signal. Characterizing the effect of the electron beam will result in a greater understanding of in-situ experiments in the electron microscope in order to bridge the ‘pressure-gap’. Towards the end of the project the optimized dose will be used to look at Pt/carbon catalysts for hydrogen fuel-cell applications.
