The industrial intensification has significantly increased the greenhouse gas emissions, among them carbon dioxide, which is responsible for severe environmental issues, such as global warming and climate change. In this study, a novel bimetallic dual functional material based on 10%Cu/10%CaO/Al2O3 was developed to capture and convert CO2 to methanol. Materials with fixed composition was synthesized in the laboratory and characterized using XRD, XPS, BET, and TGA. CO2 capture experiments were performed using a magnetic suspension balance up to 20 bars. Meanwhile, conversion tests were performed in a high pressure packed bed reactor at 300 °C and 40 bars. The obtained results in term of adsorption capacity revealed a high CO2 uptake. While CO2 conversion tests showed a higher selectivity towards methanol and a good conversion rate.
