In　the　quest　to　align　with　industrial　benchmarks,　a　noteworthy　gap　remains　in　the　field　of　electrochemical　nitrogen　fixation,　particularly　in　achieving　high　Faradaic　efficiency　(FE)　and　yield.　The　electrocatalytic　nitrogen　fixation　process　faces　considerable　hurdles　due　to　the　difficulty　in　cleaving　the　highly　stable　NN　triple　bond.　Additionally,　the　electrochemical　pathway　for　nitrogen　fixation　is　often　compromised　by　the　concurrent　hydrogen　evolution　reaction　(HER),　which　competes　aggressively　for　electrons　and　active　sites　on　the　catalyst　surface,　thereby　reducing　the　FE　of　nitrogen　reduction　reaction　(NRR).　To　surmount　these　challenges,　this　study　introduces　an　innovative　bimetallic　catalyst,　CuGa2,　synthesized　through　p-d　orbital　hybridization　to　selectively　facilitate　N2　electroreduction.　This　catalyst　has　demonstrated　a　remarkable　NH3　yield　of　9.82　mu　g　h-1　cm-2　and　an　associated　FE　of　38.25%.　Our　findings　elucidate　that　the　distinctive　p-d　hybridization　interaction　between　Ga　and　Cu　enhances　NH3　selectivity　by　reducing　the　reaction　energy　barrier　for　hydrogenation　and　suppressing　hydrogen　evolution.　This　insight　highlights　the　significance　of　p-d　orbital　hybridization　in　optimizing　the　electrocatalytic　performance　of　CuGa2　for　nitrogen　fixation.
