| Abstract: | CuCo-based catalysts for CO hydrogenation to higher alcohols were prepared by the ultrasound assisted reverse coprecipitation.Effects of transition elements(Zn,Mo) on the structure and catalytic performance were investigated.The catalysts were characterized by means of X-ray diffraction(XRD),N2 adsorption isotherm(BET),temperature-programmed reduction(H2-TPR) and temperature-programmed desorption(CO-TPD) techniques.The specific surface areas of the experimental catalysts were increased while the crystallite... |
