Electrocatalytic Nitrogen Reduction to Ammonia by Graphene-Supported Au4Cu2 and Au2Ag2 Nanoclusters

We synthesized Au 2 Ag 2 (PPh 3 ) 2 (PhCC) 4 and Au 4 Cu 2 (PPh 3 ) 4 (PhCC) 6 nanoclusters and found that graphene-supported Au 4 Cu 2 NCs exhibit superior ENRR performance compared to other supported or unsupported systems.
