The development of less expensive, more active, and more stable catalyst substitute for Pt/C catalysts for oxygen reduction has recently become a hot topic. In this paper, we report a new strategy to design nitrogen-doped non-precious metal catalysts via the copyrolysis of metallic iron, soybean biomass, and carbon support at high temperatures. The results show that the nitrogen in electrocatalysts...
Metallic cobalt was deposited on acetylene black to synthesize a composite Co/C by chemical reduction method. A platinum-free electrocatalyst Co–N/C(800) for oxygen reduction reaction (ORR) was synthesized by mixing the composite Co/C with urea and heat-treating at 800°C. The results from linear sweep voltammograms indicated that the Co–N/C(800) is active to ORR. The β-Co and cobalt oxides are not...
