The electrochemical conversion of N 2 at ambient conditions using renewably generated electricity is an attractive approach for sustainable ammonia (NH 3 ) production. Considering the chemical inertness of N 2 , rational design of efficient and stable catalysts is required. Therefore, in this work, it is demonstrated that a C‐doped TiO 2 /C (C‐Ti x O y /C) material derived from the metal–organic framework (MOF) MIL‐125(Ti) can achieve a high Faradaic efficiency (FE) of 17.8 %, which even surpasses most of the established noble metal‐based catalysts. On the basis of the experimental results and theoretical calculations, the remarkable properties of the catalysts can be attributed to the doping of carbon atoms into oxygen vacancies (OVs) and the formation of Ti−C bonds in C‐Ti x O y . This binding motive is found to be energetically more favorable for N 2 activation compared to the non‐substituted OVs in TiO 2 . This work elucidates that electrochemical N 2 reduction reaction (NRR) performance can be largely im...
