| Abstract: | The gold catalysts by loading gold nanoparticles on different oxide supports,namely TiO2,ZrO2,CeO2 and Fe2O3,exhibited high catalytic activity and selectivity in some oxidation reduction reactions.Application of the above gold catalysts in liquid-phase selective hydrogenation of some unsaturated compounds including unsaturated hydrocarbon,α,β-unsaturated aldehydes/ketones and nitro group compounds was summarized.The mechanisms of hydrogen adsorption and hydrogenation of different unsaturated compounds on gold catalysts were discussed.Some opinions about the research of gold catalysts,including their preparation,catalytic mechanism and measures for enhancement of their stability were given. |

| Keywords: | gold catalyst liquid-phase selective hydrogenation unsaturated hydrocarbon α β-unsaturated aldehyde α β-unsaturated ketone nitro group compound |
