The gate-opening phenomenon in ZIFs is of paramount importance to understand their behavior in industrial molecular separations. Here we show for the first time using in situ inelastic neutron scattering (INS) the swinging of the -CH3 groups and the imidazolate linkers in the prototypical ZIF-8 and ZIF-8@AC hybrid materials upon exposure to mild N2 pressure.
金属有机框架材料(ZIFs)中的开孔现象对于理解它们在工业分子分离中的行为至关重要。在此,我们首次利用原位非弹性中子散射(INS)展示了在温和氮气压力下,典型的ZIF-8和ZIF-8@AC杂化材料中-CH₃基团和咪唑连接体的摆动情况。
