Adaptive Ultramicroporous Frameworks
In article number 2302677, Qihui Chen, Maochun Hong, and co‐workers develop an acid‐base resistant ultramicroporous framework. It can sieve CO2 from humid air with the very high adsorption capacity/selectivity but the very low adsorption enthalpy. Here, the adsorbed‐CO2‐driven pore shrinkage can promote CO2 capture while the adsorbed‐H2O‐induced phase transitions...
Excessive CO2 in the air can not only lead to serious climate problems but also cause serious damage to humans in confined spaces. Here, a novel metal–organic framework (FJI‐H38) with adaptive ultramicropores and multiple active sites is prepared. It can sieve CO2 from air with the very high adsorption capacity/selectivity but the lowest adsorption enthalpy among the reported physical adsorbents....
