塩化銅(II)から調製した酸化チタン担持銅触媒のディーゼル粒子状物質燃焼活性に及ぼすアルカリ金属イオンの効果 Effect of Alkali Metal Cation on Catalytic Activity of TiO_2-Supported Copper Catalyst Derived from Copper (II) Chloride for Combustion of Diesel Particulate
Effect of alkali metal cation as an additive in catalytic combustion of Diesel particulate matter (PM)was investigated using TiO<SUB>2</SUB>-supported copper catalysts (M, Cu/TiO<SUB>2</SUB>, M: alkali metal ion) derived from copper ( II ) chloride (CuCl<SUB>2</SUB>, 2H<SUB>2</SUB>O) by the addition of Na+, K+, Rb+ and Cs+ ions, respectively. M, Cu/TiO<SUB>2</SUB> catalysts except for Na, Cu/TiO<SUB>2</SUB> showed good catalytic performance of the PM combustion be low 620 K, especially in recycle use. This is attributed to that the presence of compounds consists of M-CuCl promoted the intimate contact between MC1 and Cu species after the decomposition of M-Cu-Cl. Since K, Cu/TiO<SUB>2</SUB> among M, Cu/TiO<SUB>2</SUB> catalysts was superior in combustion temperature, potassium is presumed to act favorably for the oxidation of PM.
