On platinum-promoted

Ruthenium on platinum was found to fadhtate the oxidation of AoCOad but not eoCOad Ru> interacting water, appeared to play a role of the oxygen soiuxe, replacing Pt-OH. On the contrary, tin and molybdates on platinum promoted the oxidation of eoCOad but not AoCOad- Redox couples of tin or mol]d)denum oxides appeared to play a role of a mediator as well as the oxygen source.

The above results indicate that a relatively high oxygen coverage on platinum promotes NO(a) formation. At low temperatures, NO(a) leads to N2O via ...
