467101 Can Compressing MOFs Lead to Increased Separation Properties ? Gas Adsorption on Mechanically Constrained Soft Porous Crystals
For this purpose, we have developed a novel methodology to tune the adsorption behavior of mechanically responsive materials by coupling the effects of internal gas pressure and external mechanical pressure. In order to pilot the structural flexibility of the adsorbent during the gas adsorption, we built an experimental device to apply a mechanical pressure (up to 25 tons) on the porous material via a uniaxial press system which equally allows gas adsorption up to 15 bars.
Promising applications of this concept will be explored in this communication including mechanically induced desorption, thus avoiding thermal treatment, and pressure induced gate opening.
