Hierarchically structured sorbents were synthesized and investigated for CO2 capture from flue gas streams of coal-fired power plants under high pressure and atmospheric conditions. The insertion of Zr cations in the structure of the sorbent increased the selectivity for the adsorption of CO2 in high pressure separation processes. The presence of H2O, after atmospheric combustion, does not impair the performance of the adsorbents, because the moderate decrease in uptake rates is compensated by an increase in uptake capacity.
