Abstract

The process of TiO2 evolution from titanium diisopropoxide bis-2,4-pentanedionate precursor on nickel and titanium supports was followed by secondary ion mass spectrometry. Concentration depth profiles of rutile (TiO2) at higher temperatures showed completely different patterns for the two supports, indicating the influence of the base metal on the formation and properties of the oxide coating. The formation and surface accumulation of elemental carbon during combustion of the organic matter were followed as a function of temperature. The results obtained are in agreement with those of previous measurements by simultaneous thermogravimetry-differential thermal analysis, thermogravimetry combined with mass spectrometry and emission FTIR spectrometry.
