Abstract:
When a surface of magnesia exposed to air for a long time is irradiated with a λ < 400 nm light, NO and N2 are released into the gas phase at a constant ratio of 2: 1. This is be explained by the photodecomposition Of N2O adsorbed on the MgO surface. The spectral dependence of the effective quantum yield for the photoformation of 2NO/N2 mixture is determined; at 365 nm, the absolute quantum yield of the reaction is 0.025. The absorptance of magnesia at this wavelength is 0.04. It is established that the spectrum of formation of the 2NO/N2 mixture is similar to the absorption spectrum of magnesia.
