Chicken bone-derived N-doped porous carbon materials as an oxygen reduction electrocatalyst

• N-doped carbon material was derived from chicken bones by a facile process.
• Ca10(PO4)6(OH)2 is crucial in forming the carbon material with micropores.
• The carbon material (CCB2) exhibits high electrocatalytic performance for ORR.

In this work, a low-cost, N-doped, porous carbon material with high surface area is synthesized by carbonizing chicken bones. The N-doped porous carbon material has high specific surface area. Brunauer-Emmett-Teller (BET) surface area of obtained carbon material is ca. 769 m2g−1 with a pore size distribution in the range of 1–4 nm. Compared to a commercial Pt/C (10 wt%) catalyst, oxygen reduction in alkaline medium on the synthesized carbon material exhibits comparable electrocatalytic activity, long term-operating durability and excellent CH3OH tolerance, rendering it as a potential alternative to Pt-based catalysts.
