In order to develop effective electro catalysts for the synthesis of ammonia, we proposed to use graphite as an electrode, with a substrate of 2,4,6-diphenyl-triazine (I) coated with cobalt nanoparticles deposited on it. The electro catalytic reaction of the reduction of nitrates to ammonia1 was studied. Substrate I was synthesized from solutions of cyanuric chloride, biphenyl in n-octane in the presence of aluminum chloride. It was found that substrate I (Fig. 1) significantly increases the durability of the catalyst, and the selectivity of the process (current efficiency) decreases from 40% to 30% after the first two cycles and then remains virtually unchanged.
