Abstract: Surface emission of the low-temperature singlet oxygen (1ΔgO2) from the solid solutions of transition metal oxides with the хV2O5×уMoO3 composition was detected and explored. Thereby it was shown that the temperature interval in which low-temperature emission of the singlet oxygen was obsereved, and its amount depend on the composition of solid solutions. The ability to regenerate emission centers of 1ΔgO2 after re-adsorption of molecular oxygen by the catalyst surface was discovered. The relation between the ability of хV2O5×MoO3 to generate 1ΔgO2 and the catalytic activity of this system in the partial oxidation of n-butanol with molecular oxygen was determined and the probable routes of this process were described. It was suggested that the emission 1ΔgO2 is connected with thermal decomposition of peroxide groups.
