Cobalt nanoparticles encapsulated in nitrogen doped graphite as a highly efficient and reusable catalyst for the reduction of 4-nitrophenol

Abstract

Novel precursors including glucose, urea, and cobalt nitrate developed the Co@NC catalyst, which contains cobalt nanoparticles in nitrogen-doped graphite. The catalyst transformed 4-nitrophenol to 4-aminophenol and is reusable.
