CH4 storage and CO2 capture in highly porous zirconium oxide based metal–organic frameworks

A series of porous Zr oxoclusters-based MOFs was computationally explored for their gas storage/capture performances. The highly porous UiO-67(Zr) and UiO-68(Zr) solids show exceptionally high CH4 and CO2 adsorption capacities under operating conditions that make these thermal, water and mechanical resistant materials very promising for physisorption-based processes.
