Article Synopsis
- Fe-N-Cs are emerging as cost-effective alternatives to rare and expensive platinum group metals for use in fuel cell applications, particularly for the oxygen reduction reaction (ORR).
- The typical method of using silica templates for these materials involves hazardous hydrofluoric acid, but a new approach uses in-situ generated HF from NHHF and NaF to remove the silica safely.
- This modified method shows that a specific molar ratio of etching agents can effectively dissolve silica without damaging the porous structure of the electrocatalysts, resulting in improved performance, especially with NHHF-washed Fe-N-C catalysts achieving an exceptional onset potential of 970 mV in alkaline solutions.
