摘要：

Electrocatalytic conversion of NO into NH3 (NORR) represents an attractive route for valuable NH3 production and harmful NO removal. In this work, TiS2 is first developed as a high-efficiency NORR electrocatalyst, achieving the maximum NO-to-NH3 faradaic efficiency of 91.6% with a corresponding NH3 yield rate of 153.8 mmol h(-1) cm(-2). Theoretical computations indicate that the surface-terminated Ti active centers on TiS2 can effectively activate NO and promote the NORR protonation process with a minimized energy barrier, whilst inhibiting the competitive H-2 evolution, thereby resulting in enhanced activity and selectivity of TiS2 towards the NORR.
