主 题:Nitrogen reduction reaction Density functional theory Bismuthene Thermodynamic Electrocatalysts
摘 要:The electrochemical nitrogen reduction reaction(NRR)for the ammonia production under ambient conditions is regarded as a sustainable alternative to the industrial Haber-Bosch ***,the electrocatalytic systems that efficiently catalyze nitrogen reduction remain *** the work,the nitrogen reduction activity of the transition metal decorated bismuthene TM@Bis is fully investigated by means of density functional theory *** results demonstrate that W@Bis delivers the best efficiency,wherein the potential-determining step is located at the last protonation step of^(*)NH_(2)+H^(+)+e^(-)→*NH_(3)via the distal mechanism with the limiting potential ULof 0.26 ***,the dopants of Re and Os are also promising candidates for experimental synthesis due to its good selectivity,in despite of the slightly higher ULof NRR with the value of 0.55 ***,the candidates of Ti,V,Nb and Mo delivered the relative lower ULof 0.35,0.37,0.41 and 0.43 V might be suffered from the side hydrogen evolution *** interestingly,a volcano curve is established between ULand valence electrons of metal elements wherein W with 4 electrons in d band located at the *** phenomenon originates from the underlying acceptance-back donation ***,our work provides a fundament understanding for the material design for nitrogen reduction electrocatalysis.
