英文摘要ceni/sba-15 and lani/sba-15 catalysts were prepared by deposition-precipitation (dp) method and characterized by n-2 physical adsorption, xrd, h-2-tpr, h-2-chemisorption and tem. their catalytic performances in the ammonia decomposition reaction were tested and compared with ni/sba-15 catalyst. addition of cerium and lanthanum oxides to the ni/sba-15 catalyst caused some decrease of bet surface area and pore volume of the catalysts, but led to a promotion effect to their catalytic activity which was closely related to the ratio of cc (la)/ni. the highest conversion of ammonia could be obtained when the ce (la)/ni ratio was around 0.3. the promotion effect is more evident on ceni/ sba-15(0.3) than on lani/sba-15(0.3) catalyst under identical reaction conditions. the ceni/sba-15 and lani/sba-15 catalysts show smaller nickel particle size and easier reducibility in comparison with the ni/sba-15 catalysts.
