摘要
采用不同方法合成了一系列的贵金属Pt单金属及多金属催化剂,研究了它们对甘油选择性催化氧化反应的催化性质.催化剂9%Pt-5%Bi/C可以有效地将甘油选择性催化氧化成二羟基丙酮,当反应温度为55℃,反应时间为50h时,甘油全部转化,二羟基丙酮的产率为50.05%.
A series of catalysts were prepared by different means, and their catalytic properties on the selective oxidation of glycerol were studied. The results showed that the catalyst 9%Pt-5%Bi/C can have satisfying effects on the selective oxidation of glycerol when the main product was dihydroxyacetone. When the reaction time was 50 h, the temperature was 55 ℃, glycerol converted completely, and the yield of dihydroxyacetone was 50.05%.
