| 英文摘要 | effects of ceo2 addition on the catalytic performance of ni/al2o3 catalysts for ammonia decomposition to hydrogen were investigated by activity studies and some physico-chemical methods like n-2-adsorption/-desorption, h-2-chemisorption, x-ray diffraction (xrd), h-2 temperature-programmed reduction (h-2-tpr) and nh3 temperature-programmed surface reduction (nh3-tpsr). the results showed that the addition of ceo2 greatly improved the catalytic activity and stability of ni/al2o3 catalysts for ammonia decomposition to cox-free hydrogen. 98.3% nh3 conversion and 32.9 mmol/(min g(cat)) h-2 formation rate were achieved over ceo2 promoted ni/al2o3 catalyst at 823 k and 30 000 ml/(h g(cat)) nh3 space velocity. the characterization results indicate that the addition of ceo2 enlarged the catalyst pores, moderated the interaction between ni and alumnia, suppressed ni-0 crystallites from sintering, and improved the recombinative desorption of n adatoms from the ni-0 surface.
