Surface| Zusammenfassung: | Structure and properties of the oxide films Fe/Ti=1:1 prepared by a sol-gel method from iron(III) chloride and titanium tetraisopropoxide were studied using TEM, EDX, and XRD as well as optical absorption and Mőssbauer spectroscopy. The films have been shown to be Fe2Ti2O7 phase. They demonstrate a photocatalytic activity in the processes of dichloroacetic acid photomineralization and N2 photoreduction under UV as well as visible light irradiation. In the presence of ethanol and traces of oxygen, dinitrogen is reduced to ammonia and nitrate-ion, hydrazine being found to be an intermediate product. |
