The optimum loading amount of the most effective Co was 0.15 wt% in metal equivalent. The promotion effect of transition metal additives in the SnO_2 system originated in the increasing selectivity with the suppression of undesirable oxidation of C_2H_4 by 0_2. The promotion effect of Co was observed with catalysts calcined at 600℃ in the reaction condition which had more oxidizing (higher (NO+O_2)/C_2H_4) and severer for the NO reduction (lower NO/O_2) composition., 長崎大学工学部研究報告 Vol.27(48) p. 173-177, 1997}, pages = {173--177}, title = {Effect of Transition Metal Additives on Catalytic Activity of SnO_2 for the Selective Reduction of NO with C_2H_4}, volume = {27}, year = {1997} }
