Minimizing the use of platinum (Pt) in catalysts for the oxygen reduction reaction (ORR) is critical for the commercial application of fuel cells. Here, we report a highly active carbon-supported catalyst with a low loading of Pt nanoparticles (Pt/C-

The performance of the Electro-Fenton (EF) process for contaminant degradation depends on the rate of H2O2 production at the cathode via 2-electron dissolved O2 reduction. However, the low solubility of O2 (≈1 × 10−3 mol dm−3) limits H2O2 prod
