摘要: Abstract A Ru/AlO(OH) catalyst was prepared by co-precipitation and characterised X-ray diffraction (XRD), photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), thermo-gravimetry (TG), Fourier transform infrared (FT-IR). Its catalytic performance tested in the selective hydrogenation of citral. The results showed that combination water obviously improved activity its selectivity to geraniol nerol. Introducing organic additives increased hydrophilicity metal particles, which favoured adsorption citral C O bond over conjugated bond, improving inhibiting further maximum yield nerol (81%) achieved with ethylenediamine as an additive.
