The catalytic oxidation of NH3 is currently a key industrial synthetic process for HNO3 production. The reaction is known to be very fast and highly efficient [1]. The major products of the reaction on Pt surfaces are H2O and N2 or NO, depending on reaction temperature and the relative concentration of NH3 and O2 according to the following stoichiometries:
$$ 4N{H_3}+3{O_2} \to2{N_2}+6{H_2}O $$
$$ 4N{H_3}+5{O_2}\to 4NO + 6{H_2}O.$$
