Co,N-doped carbon sheets prepared by a facile method as high-efficiency oxygen reduction catalysts

Abstract

The Co,N-doped carbon sheets as high-efficiency ORR catalysts were prepared by a facile process.

An ‘active site anchoring’ strategy for the preparation of PBO fiber derived carbon catalyst towards an efficient oxygen reduction reaction and zinc–air batteries

“…6,7 Therefore, researchers are committed to obtaining platinumfree catalysts with a high activity and low costs, such as transition metal oxides, transition metal-modied carbon materials and heteroatom-doped carbon materials. [8][9][10][11][12] Among them, iron/ nitrogen co-doped carbon-based (Fe/N-C) electrocatalysts are considered the most promising ORR catalytic material to replace platinum because of their low cost, good conductivity, and high catalytic activity. [13][14][15] Iron/nitrogen-carbon electrocatalysts are usually prepared by the physical mixing of iron salts and carbon and nitrogen precursor compounds, followed by pyrolyzing at a high temperature.…”
