The effect of surface OH-population on the photocatalytic activity of rare ea…
Abstract. Commercial TiO2 (P25, from Degussa) was modified with variable amounts of La, Ce, Y, Pr, Sm (generally rare earth (RE)), by thermal treatment of physical mixtures of TiO2 and the nitrates of the various RE. Doping of P25 with RE, combined with calcination at 600 or 800 ◦C, yields materials with surface areas ranging from ∼10 to 50 m2/g, and an anatase to rutile phase ratio ran…

Cu/Al2O3 catalysts for soot oxidation: Copper loading effect
Abstract. Cu/Al2O3 catalysts with metal loading from 0.64 to 8.8 wt.% have been prepared and characterized by different techniques: N2 adsorption at 196 8C (BET surface area), ICP (Cu loading), XRD, selective copper surface oxidation with N2O (Cu dispersion), TPR-H2 (redox properties), and XPS (copper surface species). The catalytic activity for soot oxidation has been tested both in air a…

Power-bench demonstration of the Pt-catalysed C3H6-SCR of NOx in a diesel exh…
Abstract. The SCR of NOx by C3H6 using a 0.1 wt.% Pt/Al2O3 catalyst has been successfully performed under real diesel gas streams in a power bench. The influence of some experimental variables affecting NOx, CO, and THC conversions, such as hydrocarbon concentration, reaction temperature and space velocity effect, are discussed. 96% NOx conversion has been reached under optimum conditions. …
