A method of producing hydrogen from ammonia includes exposing ammonia to a rare-earth/NiO/AlOnanocomposite material. The rare-earth/NiO/AlOnanocomposite material catalyzes the decomposition of ammonia into hydrogen. The rare-earth/NiO/AlOnanocomposite material is in the form of rare-earth doped NiO nanoparticles distributed on a AlOmatrix. The rare-earth doped NiO nanoparticles include a rare-earth dopant selected from the group consisting of La, Ce, Nd, Sm and combinations thereof, at a concentration of 1 to 20 wt. % based on the total weight of the rare-earth/NiO/AlOnanocomposite material. The rare-earth doped NiO nanoparticles are spherical with an average diameter in a range from 1 to 200 nm. The rare-earth/NiO/AlOnanocomposite material achieves a 90% or greater conversion of ammonia to hydrogen, based on the total amount of ammonia, at a temperature less than or equal to 550° C., when used to catalyze the decomposition of ammonia.
