One-pot synthesis of cobalt-coordinated N-doped carbon catalysts via co-synthesis of ionic liquids and cobalt porphyrins.

Cobalt-coordinated N-doped carbon (CoNC) was fabricated by heating cobalt porphyrins and ionic liquids. The prepared catalysts displayed superior catalytic capacity for the direct oxidation of ethylbenzene, and unprecedented stability was obtained even after six runs with a similar catalytic performance.
