Jang, Auteur Année de publication : 2010 Article en page(s) : pp. 8433-8438 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Catalyst Titanium oxide Plasma Calcining Résumé : This study focuses on investigating the effects of conventional calcination procedures and O2 plasma treatments on the metal precursor-support interaction (MPSI) of 1 wt % Pd/TiO2. MPSI is likely a strong precursor to the metal-support interaction of supported metal catalysts. The authors identify H2-DSC (H2-differential scanning calorimetry) as a sensitive and effective technique for measuring and differentiating the MPSIs of PdO and palladium nitrate with TiO2. At room temperature, the effect of O2 plasmas on MPSI is stronger than the effect of high-temperature calcination. In addition, O2 plasma treatments can increase the strength of the MPSIs of both supported PdO and palladium nitrate while minimizing the detrimental effects of high-temperature calcinations on the composition of supported metal precursors.
