The ecological impact of carbon dioxide (CO2) in the atmosphere necessitates a reduction of CO2 emissions and demands utilization strategies. Hydrogenation processes may contribute to reduction of CO2 emissions, and furthermore can be used in energy storage. The possible hydrogenation processes methanation and methanol (CH3OH) synthesis are investigated. Due to thermodynamic stability of CO2 large scale hydrogenation needs robust catalysts with sufficient activity at moderate reaction conditions, which are easy to prepare, easy to recycle, and stable for long term usage. Exemplarily, Ni doped MgO catalysts offer great performance in methanation and can easily be recycled in basic-oxygen-furnaces in either steel or copper industry.
