In this project, we try to elucidate the promoting effects of reducible oxides on CO2 conversion towards methanol using a noble metal catalyst system. Various reducible oxides will be investigated to determine if similar behaviour exist within these promotional effects.
To transition toward a more renewable future, chemical processes need to move away from fossil fuels as a feedstock. The use of CO2 as an alternative feedstock can both provide a different carbon source for the chemical industry, and reduce CO2 emissions. Methanol is an important starting material for the chemical industry and could be produced by the hydrogenation of CO2. Reducible oxides have been shown to play interesting roles as promotors in this reaction, boosting catalytic activity and steering selectivity. However, very little is yet understood about this influence and how this can be explained by the properties of the oxide.
Therefore, this project will be aimed to elucidate the effects that reducible oxides have in the catalytic hydrogenation of CO2 to methanol. The oxides influence in different aspects of the catalytic process, from synthesis to catalysis, will be investigated. Key characterization techniques will aim to determine the promotor species during actual high pressure reaction conditions, like operando XAS. Other characterization techniques of interest include TPO/R, EM, and XRD.
