AbstractWe synthesize Co single atoms anchored on N-doped carbon (Co-SAs/NC) by carbonizing a mixture of cobalt acetate, tartaric acid, and polyvinylpyrrolidone. The Co-SAs/NC exhibits nitrogen reduction reaction (NRR) activity, affording an NH3 yield rate of 9.7 mu g h(-1) mg(cat.)(-1) with a Faradaic efficiency (FE) of 7.5% at -0.45 V (vs RHE) in 0.005 M H2SO4. After laser-irradiation treatment, the Co-SAs/NC indicates an enhanced NH3 yield rate (16.9 mu g h(-1) mg(cat.)(-1)) and FE (18.8%) at -0.25 V (vs RHE) in 0.005 M H2SO4. The improved NRR activity is due to more exposed Co-N-3 sites on Co-SAs/NC after the laser-irradiation treatment.
