My goal is to develop new methods of nanoparticle production and new materials based on them. Application areas are hydrogen storage, chemical sensors, catalysts, photovoltaics and water splitting. Focussing on non-conventional techniques, mainly aerosol-based methods, my students and I are busy with creating inorganic materials and nanostructures that have never been produced before They open new perspectives for sustainable technologies. Together with a spin-off company we recently founded, I want to bring these new approaches to application. Among others, we can produce inorganic high surface area materials of a wide variety of compositions and arbitrary mixtures thereof, by combining spark ablation with electrospinning of nanofibres. Our capabilities of nanoparticle production go down to the sub-nano domain of atomic clusters, and we are studying some of their properties.
