摘要:
The successful construction of highly stable and active platinum nanoparticles (Pt NPs) within the confined cavity of a three-dimensional porphyrinic nanocage is presented in this study. The flexible porphyrinic nanocage containing eight N-heterocyclic carbene (NHC) precursors was prepared using a metal-carbene-templated ring-closing metathesis (RCM) approach as new capping materials for the fabrication/stabilization of Pt NPs. Notably, the NHC-stabilized Pt NPs within the porphyrinic nanocage exhibited high catalytic activity for selective oxidation of 2-chloroethyl ethyl sulfide to nontoxic 2-chloroethyl ethyl sulfoxide with excellent stability and recyclability.
