Fig. 4: Improvement of NRR performance and NRR active mechanism of AgNDs.
From: Efficient electrocatalytic nitrogen reduction to ammonia with aqueous silver nanodots
a LSV curves of Ov-TiO2/Ti with and without AgNDs incorporation in Ar- and N2-saturated 0.1 M Na2SO4 solutions (pH = 10.5). b The dependence of NH3 yield and faradaic efficiency of AgNDs catalyst on the applied potential using Ov-TiO2/Ti current collector. The error bars correspond to the standard deviations of three independent measurements. c The top view of the optimized structures of Ag (111) plane along the lowest energy NRR reaction pathway for N2 conversion into NH3 (Ag: cyan, N: blue, and H: white). d Free-energy diagram of the N2 reduction reaction at the optimized Ag (111) plane.
