Pyrrolic N wrapping strategy to maximize the number of single-atomic Fe-Nx sites for oxygen reduction reaction

Gil-Seong Kang et al.

Summary: This study developed a strategy to increase the number of Fe-N-x active sites in Fe-N-C catalysts by enhancing the electrostatic interactions. By dispersing pyrrolic N-rich carbon (pNC) on the surface of a metal-organic framework (MOF), the number of active sites on the derived hollow carbon framework dramatically increased. The synthesized catalysts were applied in an anion exchange membrane fuel cell (AEMFC) and exhibited satisfactory performance in terms of current density and power density.

Electrocatalysts development for hydrogen oxidation reaction in alkaline media: From mechanism understanding to materials design

Yang Qiu et al.

Summary: Anion exchange membrane (AEM) fuel cells have attracted attention due to the use of non-precious metals as catalysts, but the reaction kinetics of hydrogen oxidation reaction (HOR) in alkaline systems is much slower than in acidic systems. Major theories for understanding this include pH dependent hydrogen binding energy and the bifunctional theory based on both hydrogen and hydroxide adsorption. Different HOR mechanisms in acid and base electrolytes are discussed, along with strategies for catalyst design in alkaline environments.
