Abstract
Carbon dioxide capture from air (CO2 ∼ 400 ppm) on powder Ce0.8Zr0.2O2 solid solution and subsequent conversion to dimethyl carbonate is described. The process includes three steps, namely (i) adsorptive enrichment of CO2 on the oxide surface, (ii) transformation under mild conditions (p = 1 bar; T = 70–110 °C) by subsequent gaseous methanol feeding in inert gas, and (iii) desorptive release of the products by treatment with pure inert gas.
