Abstract: A noble method is provided to produce hydrogen while controlling the generation of hydrogen by preventing oxidation of pure metal nanoparticles using a block copolymer and performing an oxidation reaction of the metals only when the metal nanoparticles are exposed to water, thereby decomposing hydrogen from water, a hydrogen produced by the method is provided. In a hydrogen producing method comprising the steps of: (a) forming metal nanoparticles from a metal salt using a block copolymer; and (b) exposing the metal nanoparticles to water to generate hydrogen by an oxidation reaction of the metal nanoparticles with water, the hydrogen producing method is characterized in that a block copolymer micelle process is used, the block copolymer micelle process comprising a process of forming metal nanoparticles by allowing the block copolymer to form a micelle by self-assembly and adding a metal salt selected from the group consisting of iron(Fe), nickel(Ni), and cobalt(Co) into the micelle in the step(a). The method comprises forming the micelle by self-assembly when dissolving the block copolymer into a solvent. The block copolymer is at least one selected from the group consisting of poly(styrene-block-4-vinylpyridine), poly(styrene-block-2-vinylpyridine), poly(styrene-block-ethylene oxide), poly(styrene-block-methacrylic acid), and poly(styrene-block-acrylic acid). The solvent is at least one selected from the group consisting of water, toluene, N,N-dimethylformamide, ethylacetate, methylene chloride, chloroform, acetone, dimethylsulfoxide, N-methylpyrrolidone, dioxane, tetrahydrofuran, methyl ethyl ketone, acetonitrile, methanol, and ethanol. Further, the metal salt is acetate salt or chloride salt.
