Polypyrrole-coated palladium nanoparticles could be directly generated inside a metal–organic frameworks. The resulting MOF composites exhibited higher semihydrogenation capability than the analog composite without polypyrrole coating.

In this study, we demonstrated the direct synthesis of sodium dihydrogen phosphate (PA) containing palladium nanoparticles (PdNPs) supported on a metal–organic framework (MOF). The resulting composite containing PA molecules coexisting...
