Two‐Dimensional Ti<sub>3</sub>C<sub>2</sub> MXene Supported RuCo Catalyst for Improving the NH<sub>3</sub> Yield of Electrocatalytic Nitrate Reduction Reaction
Abstract To enhance the electrochemical synthesis of ammonia performance by accelerating the reaction kinetics of electrocatalytic Nitrate reduction reaction (NO 3 − RR), it is crucial to develop electrocatalysts with high acitiity and selectivity of NO 3 − RR. Herein, a Ru‐doped Co‐Ti 3 C 2 catalyst was prepared for NO 3 − RR in this work. In 0.1 M KOH & 0.1 M KNO 3 electrolyte, the Ru doped Co‐Ti 3 C 2 (nRu:nCo = 2:8, RuCo‐Ti 3 C 2 ‐2:8) achieved a Faraday efficiency (FE) of 96.48% and an ammonia yield of 2261.99 µg cm −2 h −1 at −0.4 V vs. RHE. Compared with the Co‐MXene catalyst and the Ru doped Co‐Ti 3 C 2 catalysts of other compositions, RuCo‐Ti 3 C 2 ‐2:8 exhibited better ammonia yield and high FE. Moreover, the RuCo‐Ti 3 C 2 ‐2:8 catalyst exhibited excellent stability of electrocatalytic NO 3 − RR.
