摘要： The ethanol synthesis catalyst is a catalyst for synthesizing ethanol from carbon dioxide, and includes at least one carrier selected from the group consisting of ZrO2, Al2O3, and TiO2; Fe and Cu supported on the carrier; and Na and/or K supported on the carrier. In one embodiment, the catalyst including iron oxide and copper oxide as the Fe and Cu supported on the carrier can be used, hydrogen can be supplied to the catalyst to reduce iron oxide and copper oxide, and a reaction gas containing CO2 can be supplied to the catalyst after reduction to obtain ethanol from CO2.
