摘要：A new microporous metal organic framework (MOF) with formula {Co-2(oba)(4)(3-bpdh)(2)}4H(2)O [oba = 4,4'-oxybis(benzoic acid); 3-bpdh = N,N'-bis-(1-pyridine-3-yl-ethylidene)-hydrazine] was assembled, and its morphology was found to undergo a microrod-to-nanosphere transformation with temperature variation. Core shell Au@Pd functional nanoparticles (NPs) were successfully encapsulated in the center of the monodisperse nanospheres, and Pt NPs were well -dispersed and fully immobilized on the surface of Au@Pd@lCo to build the Pt/AupPdp1Co composites, which exhibited NPs catalytic activity for the reverse water gas shift reaction. The core shell AupPd NPs in MOF significantly enchanted the CO selectivity of the catalyst, and the Pt NP loading on the surface of the nanosphere afforded a desirable CO2 conversion.
