Transforming carbon dioxide into valuable chemicals and fuels, is a promising tool for environmental and industrial purposes. Here, we present catalysts comprising of cobalt (oxide) nanoparticles stabilized on various support oxides for hydrocarbon production from carbon dioxide. We demonstrate that the activity and selectivity can be tuned by selection of the support oxide and cobalt oxidation state. Modulated excitation (ME) diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) reveals that cobalt oxide catalysts follows the hydrogen-assisted pathway, whereas metallic cobalt catalysts mainly follows the direct dissociation pathway. Contrary to the commonly considered metallic active phase of cobalt-based catalysts, cobalt oxide on titania support is the most active catalyst in this study and produces 11% C2+ hydrocarbons. The C2+ selectivity increases to 39% (yielding 104 mmol h(-1) g(cat)(-1) C2+ hydrocarbons) upon co-feeding CO and CO2 at a ratio of 1:2 at 250 degrees C and 20 bar, thus outperforming the majority of typical cobalt-based catalysts. Catalytic conversion of CO2 into valuable hydrocarbons is a promising way to mitigate climate change. This work uncovers that cobalt oxide nanoparticles on a titania carrier produce more C2+ hydrocarbons than their metallic cobalt counterpart by following a different reaction mechanism.
