1. A method for manufacturing a catalyst for ammonia decomposition, the method comprising:
(a) preparing a mixture comprising water, alcohol, an active metal precursor for ammonia decomposition, and a metal oxide;
(b) obtaining a solid by subjecting the mixture to solvothermal synthesis using water and alcohol and
(c) drying the obtained solid,
wherein in the (a), the content of the active metal precursor for ammonia decomposition is in a range of 1 to 10 parts by weight with respect to 100 parts by weight of the metal oxide, and the volume ratio of the alcohol to the water is in a range of 0.5 to 1.5, and
wherein in the (b), the solvothermal synthesis is performed at a temperature in a range of 120° C. to 200° C.
