摘要: Bimetallic Au-Pd nanoparticles(NPs) with synergistic effect between Au and Pd atom have shown excellent catalytic activity toward benzyl alcohol oxidation. The catalytic activities of metal NPs supported within metal-organic frameworks (MOFs) are affected by the electronic interactions between metal NPs and MOFs. Taking the advantages of ultrathin nanosheets, we confine the highly dispersed Au-Pd NPs within ultrathin nanosheets of MOF-Ni(NMOF-Ni) to fabricate AuxPdy@NMOF-Ni as catalysts. Under base-free and atmospheric pressure conditions, the as-prepared AuxPdy@NMOF-Ni catalysts exhibit superior activity and selectivity for benzyl alcohol oxidation. This work highlights the synergistic effects among different components in composite catalysts effectively improving the activity and offers a new way for designing efficient catalysts toward benzyl alcohol oxidation.
