Abstract
We discovered an in situ auto-reduction method to embed silver nanoparticles onto a nanoporous carbon
(NC) derived from the zeolitic imidazole framework-8 (ZIF-8), without any requirement of the reducing
agents. The detailed analysis demonstrated the formation of Ag NPs by the replacement of the metallic
Zn residue in the NC with Ag ions. The synthesized Ag@NC exhibited a superior catalytic activity toward
the reduction reaction of 4-nitrophenol into 4-aminophenol.
