Heterogeneous Nitrogen‐doped Graphene Catalysed HOO− Generation via a Non‐radical Mechanism for Base‐free Dakin Reaction

Abstract A heterogeneous nitrogen‐doped graphene catalytic pathway for H 2 O 2 activation to generate alkaline hydrogen peroxide (HOO − ) through a non‐radical mechanism was reported. Remarkably, the heterogeneous catalytic procedure has been used for the evergreen and environmentally Dakin reaction without using any transition metals, homogeneous bases, ligands, additives or promoters, completely. The study of catalyst structure and catalytic activities indicate that the most active sites are created by the graphitic N atoms at zig‐zag edges of the sheets. In addition, N as dopant element changes the reactivity of the neighbour C atoms, and leads to the formation of carbon‐hydroperoxide (C−(HOOH)) and C−O* (C−O − ) transition state species on the graphene surface in catalytic the reaction. magnified image
