Ammonia oxidation reaction investigated on carbon-supported PtRu alloys. Various Pt:Ru atomic ratios were studied: 100:0, 90:10, 70:30 and 50:50. Pt90Ru10/C catalyst is the most active in electrochemical and fuel cell experiments. Main products of ammonia oxidation are nitrogen, nitrate and nitrite. 10 at% of Ru improves the reaction by supplying OHads.
