Tóm tắt

AbstractA convenient method for the confined incorporation of highly active bimetallic PdCo nanocatalysts within a hollow and porous metal–organic framework (MOF) support is presented. Several chemical conversions occur simultaneously during the one‐step low temperature pyrolysis of well‐designed polystyrene@ZIF‐67/Pd2+ core–shell microspheres, where ZIF (zeolitic imidazolate framework) is a subclass of MOF: the polystyrene core is removed, resulting in a beneficial hollow and porous ZIF support; the ZIF‐67 shell acts as a well‐defined porous support and as a felicitous Co2+ supplier for metal nanoparticle formation; and Pd2+ and Co2+ are reduced to form catalytically active bimetallic PdCo nanoparticles in the well‐defined micropores, inducing the confined growth of PdCo nanoparticles with excellent dispersity.

A small amount of Pd2+was loaded within the micropores of the ZIF-67 shell when a methanolic solution of Pd(OAc)2was used as a Pd2+source instead of a methanolic solution of Na2PdCl4(see the Supporting Information Figure S6 for detailed information).

The decomposition temperature of ZIF-67 varies depending upon the heating environments (for example under an air or N2atmosphere). See:
