1results about How to "Improve electrode performance" patented technology

This application relates to the field of electrocatalysts and their preparation technology, specifically to a phosphorus-doped cobalt-molybdenum alloy electrode, its preparation method, and its application. This application solves the problem of low Faradaic efficiency and yield in existing electrocatalytic conversion of nitrate to ammonia. The catalyst for nitrate-to-ammonia reduction with a nanosheet structure obtained by phosphating a sample prepared from a Co and Mo composite exhibits excellent Faradaic efficiency and yield in nitrate-to-ammonia reduction. Test results show that the prepared P-CoMo / NF nanoalloy catalyst achieves an ammonia yield as high as 13700.49 μg h⁻¹ in a mixed solution of 1 mol / L KOH and 0.1 mol / L KNO₃ at -0.5 V vs. RHE. ‑1 cm ‑2 The Faraday efficiency remained at 91.69%. Furthermore, the ammonia yield and Faraday efficiency remained stable over 10 cycles at -0.5V vs. RHE.
