© 2019 The Chemical Society of Japan We report, for the first time, metal (Pd) nanocrystals (NCs) covered with a 2D flexible metalorganic framework (MOF) of [Zn(NO2-ip)(bpy)]n (NO2-ip: 5-nitro-isophthalate, bpy: 4,4¤-bipyridine). The hybrid materials were characterized by powder X-ray diffraction measurements and transmission electron microscope techniques. The CO2 sorption and hydrogen storage properties revealed that both the flexible porous character of the MOF and the hydrogen absorption ability of Pd NCs were compatible in the hybrid.
