Abstract

High Resolution Image Download MS PowerPoint Slide The development of nonprecious metal (NPM) catalysts for oxygen reduction is critical to advancing the widespread adoption of fuel cells. Among NPM catalysts, single-atom catalysts derived from the pyrolysis of Fe, N, and C-containing precursors are well-known for their activity. Additionally, 14-membered macrocyclic Fe complexes have garnered significant attention for their catalytic potential. In this study, we investigated a hybrid catalyst comprising a 14-membered macrocyclic Fe complex and an Fe/N/C catalyst synthesized via the pyrolysis of Fe-containing polyimide nanoparticles as an NPM oxygen reduction catalyst. Kinetic studies conducted using rotating ring-disk electrode (RRDE) voltammetry in both acidic and alkaline media revealed that this hybrid catalyst exhibits exceptional activity. Furthermore, fuel cell tests with a proton exchange membrane demonstrated promising performance, highlighting the potential of this hybrid approach for practical applications.
