Carbon Nanoframes: Well‐Dispersed ZIF‐Derived Co,N‐Co‐doped Carbon Nanoframes through Mesoporous‐Silica‐Protected Calcination as Efficient Oxygen Reduction Electrocatalysts (Adv. Mater. 8/2016)

The performances of metal and nitrogen co-doped carbon electrocatalysts obtained by pyrolysis suffer enormously from the irreversible fusion and aggregation of catalyst particles during pyrolysis. On page 1668, T. Zhang and co-workers develop a mesoporous SiO2-protected calcination strategy for the synthesis of a dispersive Co,N-co-doped carbon framework with outstanding oxygen reduction reaction (ORR) electrocatalytic activity from Co,Zn-ZIF precursors. This strategy can be also suitable for other heteroatom-doped carbon electrocatalysts prepared by pyrolysis.
