Novel synthesis of N-doped graphene as an efficient electrocatalyst towards oxygen reduction

Nitrogen-doped graphene （NG） was successfully synthesized by a novel, facile, and scalable bottom-up method. The annealed NG （NG-A） possessed high specific surface area and a hierarchical porous texture, and exhibited remarkably improved electrocatalytic activity in the oxygen reduction reaction in both alkaline and acidic media. Ab initio molecular dynamic simulations indicated that rapid H transfer and the thermodynamic stability of six-membered N structures promoted the transformation of N-containing species from pyrrolic to pyridinic at 600 ℃ In O2-staturated 0.1 M KOH solution, the half-wave potential （El/2） of NG-A was only 62 mV lower than that of a commercial Pt/C catalyst, and the limiting current density of NG-A was 0.5 ***-2 larger than that of Pt/C. Koutecky-Levich （K-L） plots and rotating ring-disk electrode measurement indicated a four-electron- transfer pathway in NG-A, which could be ascribed to its high content of pyridinic N.

Designing earth-abundant electrocatalysts with high performance towards water oxidation is highly decisive for the sustainable energy technologies. This study develops a facile natural corrosion approach to fabricate nickel-iron hydroxides for water oxidation. The resulted electrode demonstrates an outstanding activity and stability with an overpotential of 275 mV to deliver 10 mA·cm^(−2). Experimental and theoretical results suggest the corrosion-induced formation of hydroxides and their transformation to oxyhydroxides would account for this excellent performance. This work not only provides an interesting corrosion approach for the fabrication of excellent water oxidation electrode, but also bridges traditional corrosion engineering and novel materials fabrication, which would offer some insights in the innovative principles for nanomaterials and energy technologies.
