Abstract: Disclosed are a method for preparing metal nanocatalyst particles and a method for preparing a nanometal support composite catalyst. The manufacturing method of the metal nanocatalyst particles comprises the steps of forming a metal-olate complex compound by making metal precursors react with an olate-based surfactant; forming pre-metal nanoparticles by heating the metal-olate complex compound; and activating the pre-metal nanoparticles in electrochemistry manners, therefore being capable of making the metal nanocatalyst particles. The manufacturing method enables the mass production of a metal nanocomposite catalyst and can be applied to the actual electrochemistry application field.
