Shifting electrochemical oxygen reduction towards 2e –  pathway to hydrogen peroxide (H 2 O 2 ), instead of the traditional 4e –  to water, becomes increasingly important as a green method for H 2 O 2  generation. Here, through a flexible control of oxygen reduction pathways on different transition metal single atom coordination in carbon nanotube, we discovered Fe-C-O as an efficient H 2 O 2  catalyst, with an unprecedented onset of 0.822 V versus reversible hydrogen electrode in 0.1 M KOH to deliver 0.1 mA cm −2  H 2 O 2  current, and a high H 2 O 2  selectivity of above 95% in both alkaline and neutral pH. A wide range tuning of 2e – /4e –  ORR pathways was achieved via different metal centers or neighboring metalloid coordination. Density functional theory calculations indicate that the Fe-C-O motifs, in a sharp contrast to the well-known Fe-C-N for 4e – , are responsible for the H 2 O 2  pathway. This iron single atom catalyst demonstrated an effective water disinfection as a representative application.
