CO2 valorisation as a low, or even negative-cost feedstock, has gained a lot of attention recently. The use of CO2 as C-containing feedstock can be a means for the abatement of CO2 as an environmental pollutant during the search for, and scale up of, fossil fuel alternatives. Hydrogenation of CO2 is a reaction with the potential to be applied in this concept, because of its ability to reduce the negative impacts of CO2 point sources. Required hydrogen for this reaction can be produced by water electrolysis using surplus energy from renewable energy sources, which – as a result – allows demodulation of the mismatch in renewable electricity demand and supply.

During my research I will focus on support, alloying and promoter effects and active sites in CO2 hydrogenation in order to spatially resolve the activity of CO2 hydrogenation over supported Ni catalysts. To achieve this, we will use both ab-initio simulation methods and spectroscopic techniques, such as vibrational, electronic, microscopic and synchrotron-based methods. This will allow us to gain topological information of adsorbed species, which can potentially reveal the location of the active sites, and their relative amount.
