The Role of Carbonate Formation during CO<sub>2</sub> Hydrogenation over MgO-Supported Catalysts: A Review on Methane and Methanol Synthesis
Methane and methanol are promising products for CO<sub>2</sub> hydrogenation for carbon capture and utilization concepts. In the search for effective, robust, easy-to-manufacture and stable catalysts, supported metal-based catalysts have proven advantageous. Whereas nickel for methane sy...

| description | Methane and methanol are promising products for CO<sub>2</sub> hydrogenation for carbon capture and utilization concepts. In the search for effective, robust, easy-to-manufacture and stable catalysts, supported metal-based catalysts have proven advantageous. Whereas nickel for methane synthesis and copper for methanol synthesis stand out as efficient and cost-effective catalytically active metals, the best choice of support material is still a matter of ongoing debate. This review discusses the potential of the alkaline earth metal oxide MgO as support material for CO<sub>2</sub> hydrogenation catalysts. Due to its basicity, it gives access to bifunctional catalysts as it shows pronounced CO<sub>2</sub> adsorption capacity. Whereas carbonate formation seems to be beneficial in CO<sub>2</sub> methanation, it may even have an adverse effect in methanol synthesis from CO<sub>2</sub>. |
