The activity of Pt/SiO2-TiO2 catalysts in the oxidation of phenol in solution wasinvestigated. The catalyst activity towards both phenol and COD conversion was determinated. The effect of process parameters on the catalytic activity was investigated; the catalyst was characterized before and after the test by BET, porosity, temp-programmed desorption (TPD) of NH3, XRD, and SEM measurements to determine the effect of the process conditions on its properties. The catalyst changed during the test because of leaching of the silica component and recrystalisation of the titania component.

A series of La1-xMxCoO3 (M = Sr, Ce, x = 0.0; 0.20) mixed oxides has been prepared by both ceramic and sol-gel method using citric and maleinic acids. The formation of perovskite-type structure has been shown by XRD spectroscopy. Precursors of the perovskites obtained by sol - gel method have been additionally investigated by TGA-MS to confirm the formation route steps. Catalytic activity of the La - Co perovskites have been investigated in the methanol combustion. Effects of doping element and preparation route on catalytic efficiency has been studied.
