This study reports the synthesis and characterization of nitrogen-doped graphene (N-graphene) as a metal-free electrocatalyst for the oxygen reduction reaction (ORR) in alkaline fuel cells. N-graphene was produced by chemical vapor deposition (CVD) of methane in the presence of ammonia, resulting in a flexible and transparent film with a few layers of graphene sheets. The N-graphene film exhibited superior electrocatalytic activity for ORR compared to platinum (Pt) catalysts, showing a one-step, four-electron pathway with a higher catalytic current density and better long-term stability. The N-graphene electrode also demonstrated excellent tolerance to crossover effects and CO poisoning, making it a promising candidate for fuel cell applications. The study highlights the potential of N-doped graphene as a cost-effective and efficient alternative to Pt-based catalysts, with implications for the development of other metal-free ORR catalysts.This study reports the synthesis and characterization of nitrogen-doped graphene (N-graphene) as a metal-free electrocatalyst for the oxygen reduction reaction (ORR) in alkaline fuel cells.
