The CO2 hydrogenation reaction is a promising technique to produce value-added chemicals such as methane and other hydrocarbons, and is simultaneously an interesting pathway towards a more circular economy. Recently is has been shown by Ten Have et al. that CoO/TiO2 catalysts display interesting characteristics in CO2 hydrogenation surpassing fully reduced Co/TiO2 [1]. To further study this phenomenon, this project will investigate the surface reducibility of the TiO2 support and try to gain a better understanding of the strong-metal support interactions (SMSI) involving Co and TiO2.

Techniques such as X-ray Absorption Spectroscopy (XAS) and Diffuse Reflectance Infrared Spectroscopy (DRIFTS) will be employed as they are ideal to study the Co oxidation state and surface intermediates, respectively, under relevant reaction conditions (i.e., elevated temperatures and pressures).
