摘要
对Au催化剂在不饱和烃、α,β-不饱和醛/酮、硝基化合物等不饱和化合物液相选择性加氢反应中的应用进行了述评,介绍了氢分子在Au催化剂表面的吸附机理及各类不饱和化合物在Au催化剂表面的加氢反应历程,对如何开展Au加氢催化剂的研究提出了建议,如高性能Au催化剂的制备方法研究、Au催化作用机理研究及如何提高Au催化剂的稳定性等。
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.
