PHOTOCATALYTIC PHENOL OXIDATION IN AN AQUEOUS MEDIUM USING TITANIUM AND RUTHENIUM OXIDES BASED CATALYST
In present work results of the study of photocatalytic activity of highly ordered films of ruthenium oxide (RuO2) doped TiO2 nanotube arrays (NT TiO2) are shown. The effect of the heterogenic photocatalytic process conditions on the degree of phenol oxidation was investigated. Correlation between the amount of deposited ruthenium oxide and the photocatalytic activity was determined. It was shown that the maximum rate of phenol oxidation (100% in 30 minutes) is achieved using composite films with 0.87 wt.% of ruthenium oxide and with the addition of 10 mM of hydrogen peroxide.
