Dual function materials (Ru+Na2O/Al2O3) for direct air capture of CO2 and in situ catalytic methanation: The impact of realistic ambient conditions

A dual function material (DFM) comprised of 1% Ru, 10% Na2O/γ − Al2O3 was studied for combined direct air capture (DAC) of CO2 and catalytic methanation in a temperature swing operation. In the newly proposed operation, the DFM captures CO2 (400 ppm) from air at ambient conditions. The material is t...
