Abstract. Cu/SiO2 catalysts prepared by the ammonia-evaporation (AE) method have been systematically characterized focusing on the effect of the AE temperature during catalyst preparation. It is found that the texture, composition, and structure of the calcined and reduced Cu/SiO2 catalysts were profoundly affected by the AE temperature. Based on characterizations and previous findings, the…
Abstract Ce-promoted Ru/SBA-15 catalysts were prepared by a ‘‘two solvents’’ impregnation method. In liquidphase hydrogenation of benzene, the Ce-promoted Ru/SBA-15 catalysts exhibited superior catalytic performance to the un-promoted catalyst. The optimum bulk Ce/Ru molar ratio was determined to be 0.25, at which a cyclohexene yield of 53.8% was obtained. Based on characterizations…
