Abstract: An example of the present invention provides a metal composite catalyst for ammonia decomposition and hydrogen production including a carrier; and Ni metal particles dispersed on a surface of the carrier or inside a pore, in which a content of the Ni metal particle is 15 to 70 parts by weight with reference to 100 parts by weight of the metal composite catalyst, and a diameter of the Ni metal particle is 60 nm or less. More specifically, the metal composite catalyst according to an example of the present invention is manufactured by an ultrasonic method, includes an aging step, and exhibits high efficiency and economy in ammonia decomposition and hydrogen production processes.
