Abstract
The catalytic wet air oxidation of aqueous solutions of p-hydroxybenzoic acid has been carried out over CeO2–TiO2 supported ruthenium catalysts (Ru/Ce–Ti) at 140 °C and 50 bar of air. High activity of ruthenium supported catalysts was observed. It was found that the decrease of the molar ratio Ce/Ti from 3 to 1/3, improves the activity of Ru catalysts. The activity of the samples decreases in the following order: Ru/Ce–Ti (1/3) > Ru/CeO2 ≈ Ru/TiO2 > Ru/TiO2DT51. Characterization of samples was performed by means of N2 adsorption–desorption, XRD, UV–visible, TPR, SEM and TEM.
