Abstract
The present inventions are a method for production of hydrogen which decomposes water into hydrogen by oxidation of metals only when the metals are exposed to the water, while preventing oxidation of pure metal nanoparticles using block copolymers and, in addition, hydrogen produced by the method described above. The method of the present invention has advantages of improved convenience and simplicity, achieves a preferable approach for hydrogen storage because the metal nanoparticles enclosed by the block copolymer have the ease of delivery and reaction thereof. Additionally, the method of the present invention only using water and the metal is considered eco-friendly and useful in industrial energy applications.
