UV-irradiation of silica-supported niobium oxide suspended in liquid ethanol under atmospheric oxygen led to the selective production of 1,1-diethoxyethane.The absence of oxygen or UV-irradiation with wavelengths of λ > 320 nm remarkably suppressed the reaction.The activity normalized to the number of niobium ions suggests that the active site is highly dispersed niobate species.Ethanal is the primary product of the photooxidation and 1,1-diethoxyethane is formed by acid catalysis.
