# What is the reaction mechanism of a selective catalytic reaction with urea?

What is the reaction mechanism of the following reaction:

$$\ce{4NO + 2(NH2)2CO + O2 -> 4N2 + 4H2O + 2CO2}$$

I expect that the catalyst is vanadium oxide and titanium oxide. Where can I find a detailed description of the reaction mechanism?

• Have you consulted any sources before posting here, like SciFinder, Web of Knowledge, Google Scholar? I'd assume that there is a special interest in these systems, but if wouldn't be totally surprised if extensive mechanistic studies are not yet done due to the complexity of the reaction. – Martin - マーチン Oct 11 '17 at 9:54
