Converting gaseous nitric oxide (NO) to ammonia (NH3) is important because of its environmental and industrial implications. The electrochemical transformation nitrogen (N2) NH3 faces several challenges, including a slow reaction rate low Faradaic efficiency (FE). This study presents an innovative approach by integrating NO elimination production reduction (NORR) under ambient conditions. Co Mo-based catalysts were investigated for the continuous diluted gas (1%) within proton exchange membrane (PEM) cell In NORR tests conducted without catholyte, CoMo-NC demonstrated notable performance, achieving yield 23.2 × 10−10 mol s−1 cm−2 at −2.2 Vcell FENH3 94.6% −1.6 Vcell, along with enhanced durability. Notably, this performance represents one highest achievements gas-phase room temperature.

To quickly and efficiently screen catalytic materials with both activity selectivity for the nitric oxide reduction reaction (NORR), we adopted a strategy that considers of side hydrogen evolution (HER) first. It can be seen Fe3(THT)2 (THT = triphenylene-2,3,6,7,10,11-hexathiol) has extremely excellent HER activity, Gibbs free energy change (ΔG) 0.007 eV. Based on relationship between ΔG theoretical exchange current density, all TM3(THT)2 divided into two regions: one is absolute values greater than 1 eV, other 0 eV less 1eV. Obviously, candidates have poor performance, but this precisely provides possibility obtaining NORR activity. Subsequent calculation results show maximum rate-determining step Ta3(THT)2 unexpectedly only 0.05 Therefore, may regarded as material performance selectivity. electron transfer partial density states (PDOS) analysis, it Ta plays crucial role in activation stage NO. The approach first provide new idea rapidly screening highly selective active catalysts.
