Abstract
Earth-abundant CoSe<sub>2</sub> outperforms noble metal catalysts for the selective 2e<sup>−</sup> ORR in acidic solution, enabling the stable bulk electrosynthesis of practically useful 547 ppm H<sub>2</sub>O<sub>2</sub> and the effective electro-Fenton degradation of an organic pollutant.
