Unveiling the high-activity origin of single-atom iron catalysts for oxygen reduction reaction

It is still a grand challenge to develop a highly efficient nonprecious-metal electrocatalyst to replace the Pt-based catalysts for oxygen reduction reaction (ORR). Here, we propose a surfactant-assisted method to synthesize single-atom iron catalysts (SA-Fe/NG). The halfwave potential of SA-Fe/NG i...
