Selective adsorption of dihydrogen isotopes on DUT-8 (Ni,Co) monitored by in situ electron paramagnetic resonance

Publikation: Beitrag in FachzeitschriftForschungsartikelBeigetragenBegutachtung



In situ continuous wave electron paramagnetic resonance investigation has been proven as a powerful method by employing paramagnetic Ni2+-Co2+ pairs as spin probes to follow the isotope-selective gate opening phenomenon on the DUT-8(Ni0.98 Co0.02) framework. This method is very sensitive to detect the phase transition from the closed pore to the open pore phase in response to D2 adsorption in the framework, while no phase transformation has been observed during H2 gas adsorption. More interestingly, it is also able to sense local structural changes around the spin probe during the desorption of D2 gas. Based on these evidences, the in situ continuous wave electron paramagnetic resonance method can be implemented as an efficient and non-invasive technique for the detection of dihydrogen isotopes.
