2-Butyne-1,4-diol hydrogenation over palladium supported on Zn2+-based - MOF and host-guest MOF/calix[4]arene materials

► Novel palladium supports based on metal-organic frameworks were developed. ► The network role in the 2-butyne-1,4-diol hydrogenation on Pd@MOFs was clarified. ► Pd dispersion effect on the activity of the MOF-based catalysts was examined.
