Micro-channel plates with dimension of 1 mm Γ 0.3 mm Γ 48 mm were prepared by chemical etching of stainless steel plates followed by wash coating of CeO 2 and Al 2 O 3 on the channels. After coating the support on the plate, Pt, Co, and Cu were added to the plate by incipient wetness method. Reactio
The preferential CO oxidation on a monolith Ru/Al 2 O 3 catalyst pretreated with SO 2 in the reactant gas was investigated in the presence/absence of 0.21-20 ppm sulfur compounds (SO 2 or H 2 S). In the presence of 2.1 ppm sulfur compound, CO was preferentially oxidized over the SO 2pretreated catal
