OP-III-21and selective oxidation of NH 3 to N 2 . Thereis practically neither NO nor N 2 O formation.N 2 is the main N-containing product. TPRand kinetic results show a large shift in thetemperature at which the reaction starts (550-650 K) depending on the O 2 /NH 3 ratio. Wesuggest that the influence of oxygen isrelated to its effect on the NH 3decomposition.Rh(100). It was very surprising to finddecomposition of ammonia on Rh(100), as itwas reported [2], that ammonia does notdecompose over Rh(111). TD-spectra showthe presence of NH 2 -species on the surface.In coadsorption NH 3 + O 2 experiments nosignificant shift of the desorption peak ofnitrogen was observed as was found forruthenium surface. We suppose, that unlikefor ruthenium, all the oxygen consumed inreaction with hydrogen. And at highertemperatures ~ 700 K only nitrogen atomsare present on the surface. Under oxidationconditions, nitrogen desorption is the limitingprocess. The main products are N 2, H 2 O, anda small amount of NO. NO forms only athigh temperature. We suppose, that attemperatures lower than the desorptiontemperature of nitrogen, only nitrogen atomsare on the surface. When nitrogen begins todesorb, oxygen reacts with nitrogen, formingNO. At R>1 after nitrogen desorption onlyNO, water and no N 2 or a significant amountof N 2 O were observed. At R=10 a small shiftof nitrogen desorption temperature wasfound, but not as large as for ruthenium.Fig. 1.

Conclusion. The Pt(111) and Pt(410)surfaces show high activity in theNH ads +О ads reaction accompanied by N 2and NO evolution. Various kinds ofintermediates N ads , NH ads , NH 2ads , OH ads ,HNO ads were observed in the course ofreaction. High reactivity of clean Rh(100)surface in ammonia decomposition wasfound.
