Abstract:
A method for preparing a hydrogenation catalyst by mixing a copper salt with colloidal silica to form a precipitate, washing the formed precipitate to remove anions of the copper salt from the precipitate, and impregnating the anion-removed precipitate with an alkali metal to form a hydrogenation catalyst; and a method for preparing a diol from a lactone using the hydrogenation catalyst.
