Ethanol induced method was applied to prepare Cu-Fe-Zr catalysts for conversion of syngas to higher alcohols.The catalytic performance of the catalysts induced by ethanol was superior to that of the catalyst prepared by the conventional precipitation method.Among various procedures for ethanol induced method,it was found that incorporation of ethanol in the precipitation process was the better.After incorporation of ethanol,the crystal size of CuO decreased and the reduction of copper species became easier.The better activity of Cu-Fe-Zr catalysts prepared by ethanol induced procedures was probably caused by the higher dispersion of Cu species.
