Abstract: PURPOSE: A method for generating hydrogen using a core / shell nano particle is provided to prevent a core portion from becoming oxidized by making the shell protect a pure metal nano particle of the core and to easily generate hydrogen through a reaction with water. CONSTITUTION: A method for generating hydrogen using a core / shell nano particle includes a step of eliminating a shell by contacting the core / shell nano particle with water and using an oxidation reaction. The shell is eliminated through etching or by heating the shell with a temperature over the melting point of the nano particle. Hydrogen is created through the oxidation reaction with water. The metal is titanium(Ti), iron(Fe), nickel(Ni), cobalt(Co), or aluminum(Al). The oxidation of the pure metal of the core is prevented when the shell does not react with the water. An etchant for removing the shell is hydrochloric acid, nitric acid, hydrofluoric acid, sulfuric acid, or NaOH.
