Atomic metal-nitrogen-carbon catalysts (M-N-Cs) are promising electrocatalysts for the two-electron oxygen reduction reaction (2e(-) ORR) for the green production of H2O2. However, the conventional synthetic methods of M-N-Cs typically suffer from prolonged possessing time and high energy consumption. Herein, a flash light irradiation-assisted transient pyrolysis strategy is reported for the rapid and facile synthesis of a Co-N-C catalyst consisting of atomic Co-N-4 sites supported on graphene. The resultant Co-N-C is highly active and selective as an electrocatalyst for the 2e(-) ORR, with a ...
