Method for improving selectivity of citronellol synthesized through citronellal hydrogenation

The invention discloses a method for improving selectivity of citronellol synthesized through citronellal hydrogenation. The method comprises the following steps: taking metal nano-particle @MOFs as acatalyst, performing activating treatment, and catalyzing selective hydrogenation of citronellal to produce citronellol accompanying with stirring and heating under the conditions of a hydrogen atmosphere and a pressure of 0.1-1MPa. Compared with the traditional catalytic reaction process, the method disclosed by the invention is mild in catalytic conditions and high in efficiency and yield, andhas high selectivity of the principal product citronellol. Moreover, according to the method, the nanoscale metal nano-particles are coated in the MOFs, and due to a protective effect of the MOFs structure, the metal nano-particles do not agglomerate and re-grow in the reaction process, so that the continuous high efficiency and stability of the catalyst are ensured. 本发明公开了种提高香茅醛加氢合成香茅醇选择性的方法，包括以下步骤：使用金属纳米粒子@MOFs作为催化剂，经过活化
