A significant enhancement of the selective reduction of nitrogen oxide by H2 is produced in the presence of oxygen over Au/NaY and Au/ZSM-5 catalysts by forming NO2 and N2O4 intermediates, which are eventually reduced to N2.
Explosive Thermal Decomposition Mechanism of RDX

Thin films of RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) have been subjected to transient pyrolysis using a pulsed CO2 laser in order to determine details of the thermal decomposition mechanism under conditions that simulate a thermal explosion.The first step, scission of an N-N bond, leads to formation of N2O4.The product is trapped in the solid film by rapid quenching to 77 K following the pyrolysis pulse and subsequently detected by transmission FTIR spectroscopy of the film.Product yield measurements show that 1.9 +/- 0.2 RDX molecules are destroyed for every N2O4 molecule detected in the films.Crossover experiments conducted on isotopically labeled samples containing both unlabeled and fully labeled RDX-(15)N6 show that the N2O4 product consists of a statistical mixture of (14,14)N2O4, (14,15)N2O4, and (15,15)N2O4 isotopomers.These results show that both halves of the dimer arise from separate RDX parent molecules and the explosive decomposition of RDX involves loss of only a single NO2 molecule.
