Abstract
Through the catalysis system design of in situ Ru SACs (single atoms) anchored on a rGO/NC two-dimensional interface, we successfully realized the SA-Ru@rGO/NC electrocatalyst with high metal loading density at a relatively low temperature. The largest NH3 yield of 110.1 μg h-1 mgcat-1 and FE of 17.9% were achieved at -0.3 V under ambient conditions. The electronic environment of the catalyst was regulated by the electronic metal-support interaction, and the use of SACs had the advantages of inhibiting the hydrogen evolution reaction (HER) and enhancing N2 adsorption, which effectively improved the performance of electrocatalytic nitrogen fixation.
