Supporting information for Effect of carbon xerogel activation on Fe−N−C catalyst activity in fuel cells [Dataset]

Electrochemical characterization: Figure S3 shows the linear sweep voltammetries of the different catalysts subjected to several cycles of acid leaching/thermal treatments. Catalysts were named as Fe-N-CXG-X-Tn, where X represents the activation method (CO2, H2O and KOH) and Tn indicates the number...

description Electrochemical characterization: Figure S3 shows the linear sweep voltammetries of the different catalysts subjected to several cycles of acid leaching/thermal treatments. Catalysts were named as Fe-N-CXG-X-Tn, where X represents the activation method (CO2, H2O and KOH) and Tn indicates the number of cycles of acid leaching/thermal treatment performed over each catalyst. The curve with the highest activity is plotted with a thicker line, to highlight the number of cycles giving rise to the most active catalyst.-- Under a Creative Commons license BY 4.0.
