Abstract

We report the first in situ NMR observation of ²H₂adsorbed 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 ²HNMR under controlled ²H₂gas pressure. Although HKUST-1 adsorbed very little amount of H₂at 303 K, we could successfully observe the ²H₂signal inside HKUST-1 in the NMR spectra. Furthermore, the NMR signal demonstrated that HKUST-1 interacts with H₂molecules even at ambient temperature and hydrogen pressure.
