  • Method for producing metal catalyst for preparing alcohol and metal catalyst produced thereby
    Patent number: 9579634
    Abstract: Disclosed is a method for preparing a metal catalyst having improved yield of alcohols. The method for preparing a metal catalyst for the production of alcohol from synthesis gas includes forming a metal catalyst; and irradiating the metal catalyst with gamma rays. The metal catalyst has improved yield of alcohols by stabilizing the metal catalyst through gamma ray irradiation to inhibit generation of hydrocarbons in catalytic reaction with synthesis gas.
