Claim 28:
29. A method of ammonia decomposition comprising:
(a) providing a catalyst, comprising:
a support comprising alumina and a layer adjacent to the support, wherein the layer comprises the support doped with an oxide of at least one of an alkali metal and a rare earth metal;
wherein the layer comprises aluminum (Al), cerium (Ce), and lanthanum (La); and
one or more active metals adjacent to the layer, wherein the one or more active metals comprise Ru, Pt, or Pd;
wherein a concentration of the one or more active metals is at least about 0.1, and not more than about 15 wt %; and

(b) bringing the catalyst in contact with ammonia at a temperature of at least about 400° C. and not more than about 700° C. to generate a reformate stream comprising hydrogen and nitrogen at an ammonia conversion efficiency of at least about 70% and at most about 99.9%,
wherein the ammonia is brought in contact with the catalyst at a space velocity of at least about 1 and not more than about 100 liters of ammonia per hour per gram of catalyst.
