Abstract:
1. A method for production of hydrogen (H 2 ) comprising: (a) forming metal nanoparticles from metal salts by using a block copolymer; and (b) exposing the formed metal nanoparticles to water to generate H 2 by oxidation of the metal nanoparticles with water, wherein the step (a) includes a process of: self-assembly of the block copolymer to prepare micelles; and addition of metal salts selected from the group consisting of iron (Fe), nickel (Ni) and cobalt (Co) to the inner part of the micelles to complete formation of the metal nanoparticles, wherein the formed metal nanoparticles in the step (a) have a structure of being enclosed by the block copolymer, and wherein the block copolymer, that encloses the formed metal nanoparticles, is dissolved in the water in the step (b) to expose the metal nanoparticles to water.
