Abstract：

Oxygen-doped　graphene　(O-G)　derived　from　sodium　gluconate　is　identified　as　a　promising　candidate　to　effectively　catalyze　ambient　electrohydrogenation　of　N2　to　NH3.　Electrochemical　tests　on　O-G　in　0.1　M　HCl　suggest　a　large　NH3　yield　of　21.3　μg　h-1　mgcat.-1　and　a　high　faradaic　efficiency　of　12.6%　at　-0.55　and　-0.45　V　vs.　reversible　hydrogen　electrode,　respectively,　with　strong　electrochemical　and　structural　stability　in　0.1　M　HCl.　Density　functional　theory　calculations　reveal　the　NRR　catalytic　mechanism　and　suggest　that　both　the　CO　and　O-CO　groups　contribute　more　greatly　to　the　NRR　compared　with　the　C-O　group.　©　The　Royal　Society　of　Chemistry.
