Hydroxyl-rich nanoporous carbon nanosheets synthesized by a one-pot method and their application in the in situ preparation of well-dispersed Ag nanoparticles

Abstract

Functional nanoporous carbon nanosheets (CNSs) with high surface areas have been synthesized by the pyrolysis of simple organic–inorganic layered zinc hydroxide nanosheets. The synthesized CNSs with abundant hydroxyl groups display remarkable reactivity and the capability for in situ loading with ultrafine Ag NPs, which show excellent catalytic activity toward the reduction of 4-nitrophenol (4-NP) by NaBH₄.
