Taking into account the peak current density for ammonia electro-oxidation, the highest value was obtained using PtRh/C 90:10, indicating that introducing small amounts of Rh in Pt electrocatalysts it is possible to improve the ammonia electro-oxidation. Then the use of Rh in the binary PtRh catalyst can contribute to the ammonia Sapitinib reaction.
