Abstract

We report the first in situ NMR observation of 2H2 adsorbed inside [Cu3(btc)2] (HKUST-1; btc: benzenetricarboxylate) at ambient temperature and pressure. Hydrogen adsorption behavior was investigated by hydrogen sorption analysis and in situ solid-state 2H NMR under controlled 2H2 gas pressure. Although HKUST-1 adsorbed very little amount of H2 at 303 K, we could successfully observe the 2H2 signal inside HKUST-1 in the NMR spectra. Furthermore, the NMR signal demonstrated that HKUST-1 interacts with H2 molecules even at ambient temperature and hydrogen pressure.
