Abstract:
A novel dual functional material (DFM) was developed to efficiently convert carbon dioxide into fuel, emphasizing safety, efficiency, and economy. This DFM integrates adsorption and conversion functions, featuring innovative nano-sized nickel (Ni) catalysts and titanium nanotubes (TNT) with a specific surface area of 150.9 m2/g as supports. The bifunctional material comprises MgO as an alkaline CO2 adsorbent and Ni as the methanation catalyst. Compared to TNT-based supports, the new DFM improves CO2 adsorption capacity by over 20 times. Granulated DFMs were fabricated using tablet granulation, offering practical applications for CO2 methanation in flue gas treatment.
