摘要：

Hydrogenation of citral over Ir supported on SiO2, Nb2O5 and Ir/Nb2O5-SiO2 catalysts reduced at 473 K (LT) and 773 K (HT) was studied. High selectivity to unsaturated alcohol was found, the main reaction products being geraniol and nerol. The LT catalysts show higher conversion levels, the one with a higher Nb content displays highest conversion.
