Abstract: The present disclosure relates to a method for preparing a metal catalyst deposited with a layer film by ALD process and a metal catalyst thereof. More specifically, the present disclosure is intended to inhibit sintering of catalyst particles to prevent activity decrease, thus stably maintaining high activity, and simultaneously, providing heat stability, by layer-by-layer deposition of a layer film with alternation of different inorganic films on the surface of a metal catalyst in an ALD process.
