Nitrogen and sulfur dual‐doped Mo 2 C nanosheets provide low operating potential (−86 mV for driving 10 mA cm −2 of current density). Co‐doping of N and S heteroatoms can improve the wetting property of the Mo 2 C electrocatalyst in aqueous solution and induce synergistic effects via σ‐donation and π‐back donation with hydronium cation.
