Abstract
AbstractHerein we demonstrate mesoporous frameworks interacting with carbon dioxide leading to stimulated structural contractions and massive out‐of‐equilibrium pressure amplification well beyond ambient pressure. Carbon dioxide, a non‐toxic and non‐flammable working medium, is promising for the development of pressure‐amplifying frameworks for pneumatic technologies and safety systems. The strong interaction of the fluid with the framework even contracts DUT‐46, a framework hitherto considered as non‐flexible. Synchrotron‐based in situ PXRD/adsorption experiments reveal the characteristic contraction pressure for DUT‐49 pressure amplification in the range of 350–680 kPa. The stimulated framework contraction expels 1.1 to 2.4 mmol g−1 CO2 leading to autonomous pressure amplification in a pneumatic demonstrator system up to 428 kPa. According to system level estimations even higher theoretical pressure amplification may be achieved between 535 and 1011 kPa.
Highlights
We demonstrate mesoporous frameworks interacting with carbon dioxide leading to stimulated structural contractions and massive out-of-equilibrium pressure amplification well beyond ambient pressure
We studied pressure amplification by CO2 using a series of isoreticular frameworks: DUT-48(Cu), DUT-46(Cu), DUT-49(Cu), and DUT-50(Cu) in Geometric pore volume Unit cell volume Unit cell volume DF guest-free op and cp op/cp phase [cm3 gÀ1] op phase V [nm3] cp phase V [nm3] frameworks [kJ molÀ1]
In a custom-built pressure amplifier, we demonstrate the validity of the theoretically estimated pressure amplification values
