Surface Doping of Cobalt Nanoparticles by Selenium Anion to Steer the Selectivity in Electrocatalytic Nitrate Reduction

Se doped Co nanoparticles were synthesized in electrospun carbon nanofibers (Se@Co/CNFs), which exhibit a high NH 3 FE of 94.8% and a production rate of 3.60 mmol h −1 mg cat −1 at −0.9 V vs. RHE under ambient conditions.
