Fig. 1: Illustration of pore integration strategy for the one-step ternary gas mixture purification.
From: Integration of ordered porous materials for targeted three-component gas separation
Blue and yellow ball are the impurity A and B, red ball is the target product molecule, the blue framework presents core MOF which has the specific pore sturcture for impurity A removal, the yellow framework presents shell MOF which has the specific pore sturcture for impurity B removal. When the mixed gas passes through the PIS material, the core MOF and shell MOF can cooperate to remove the impurity A and B, obtain the target product molecule by one step.
