Synergistic effect of Ce–Mg promoted Ni catalysts on 3D structured open cell foams for CO 2 hydrogenation to methane

Key Points

• Investigating the impact of Ce–Mg promoted Ni catalysts on methanation efficiency using 3D zirconia-based foams.
• Synthesis of zirconia-based open-cell foams coated with CeNi catalysts.
• Promotion of catalysts with varying MgO loadings.
• Analysis of CH4 production rates under CO2 hydrogenation conditions.
• Optimal MgO loading of 10 wt% significantly enhances CH4 production rates.
• CeNi foams without Mg promotion showed lower methanation efficiency.
