Site-density engineering of single-atomic iron catalysts for high-performance proton exchange membrane fuel cells

Feng Liu et al.

Summary: A novel polydopamine-metal complex-assisted pyrolysis strategy was used to produce catalysts with hierarchically porous carbon support and highly exposed dense-FeN4 sites, leading to significantly enhanced performance for oxygen reduction reaction (ORR) and superior power densities in proton exchange membrane fuel cells (PEMFCs). The quantitative relationship between the active site activity and ORR performance was established, highlighting the dominating role of FeN4 site density in the observed excellent PEMFC performance. This work provides a useful guidance for the design and development of novel highly-efficient single-atomic catalysts for renewable energy applications.

Summary: Polyoxometalate, after vulcanization, exhibits a two-electron feature in oxygen reduction reaction, with weakened OOH* adsorption and enhanced selectivity. In contrast, pure polyoxometalate shows a typical four-electron character. Vulcanized polyoxometalate also demonstrates photothermal-induced advanced oxidation process for degrading organic pollutants, with a Fe2+ free character and wide pH scope in comparison to traditional Fenton reaction. Additionally, the influence of structure on oxygen reduction reaction selectivity for polyoxometalate is clarified in this work.
