A Novel One-Step Hydrothermal Preparation of Ru/SnxTi1-xO2 Diesel Oxidation Catalysts and its Low-Temperature Performance.

ABSTRACT: The rutile SnxTi1-xO2 (x = 0, 0.33, 0.5, 0.67, 1) solid solution was synthesized by a one-step hydrothermal method, in which tetrabutyl titanate and Tin (IV) chloride pentahydrate were used as raw materials. A series of Ru/SnxTi1-xO2 were then prepared by the impregnation process in RuCl3 to investigate the performance and stability of CO and C3H8 oxidation. These catalysts were characterized through XRD, N2 adsorption-desorption, FT-IR, TEM, XPS, H2-TPR, and O2-TPD techniques. The effect of Sn/Ti molar ratio and hydrothermal condition on the low-temperature catalytic oxidized performance and stability of Ru/SnxTi1-xO2 were investigated. The results indicated that Ru/Sn0.67Ti0.33O2 catalyst showed an excellent activity and stability at low temperatures. The CO conversion reached 50% at 180
