The invention provides a method for catalyzing ethanol to reduce organic aldehyde compounds to prepare organic alcohol. The aldehyde compound, ethanol and CuZnAl skeleton catalyst are mixed and placed in a reaction tube, and the organic alcohol is prepared under certain catalytic conditions. The CuZnAl skeleton catalyst is prepared by an alkali corrosion method, using Tiweed alloy (CuZnAl alloy) as a raw material, and using NaOH solution to corrode the Al component in the alloy to generate an active Cu catalyst. The catalyst involved in the method has high activity, low cost and simple synthesis method; ethanol, as a hydrogen source and solvent, is a renewable bulk reagent with low price and environmental friendliness; the use of ethanol for hydrogen supply in the reaction can avoid the use of high-pressure hydrogen, and the reaction is mild It is easy to control and requires less equipment. |
