One-Step Construction of a Hollow Au@Bimetal–Organic Framework Core–Shell Catalytic Nanoreactor for Selective Alcohol Oxidation Reaction

摘要

Hollow core–shell catalytic nanoreactors have received tremendous attention due to their high mass transfer in catalysis applications. Herein, we present a novel type of well-arranged, hollow core–shell nanoreactors featured with a bimetallic porous Zn/Ni-MOF-2 shell and a tiny Au nanoparticle core. The well-designed hollow [email?protected]/Ni-MOF-2 nanoreactors were constructed through the strategy of a facile one step from a rare crystal-structure transformation without any additional template. These nanoreactors exhibit outstanding multifunctional catalysis for a broad range of alcohol oxidation under the green oxidant environment. Moreover, such hollow nanoreactors show excellent recyclability toward the selective alcohol oxidation. These findings might provide a promising platform for a general construct of various metal–organic framework-based hollow core–shell nanostructures and further highly augmented catalytic applications.
