Selective oxidation of olefin derivatives to ketones has made innovative development over palladium(0) supported on reduced graphene oxide. Compared to traditional Wacker oxidation, the novel method offers an economical and environment-friendly option by using graphene oxide (GO) as a ‘solid weak acid’ instead of classical homogeneous catalysts like H2SO4 and CF3COOH.

烯烃衍生物选择性氧化为酮的方法已在还原性氧化石墨烯上负载的钯(0)上取得了创新性的发展。与传统的Wacker氧化相比,该新方法通过使用氧化石墨烯(GO)作为“固体弱酸”,而不是像H 2 SO 4和CF 3 COOH这样的经典均相催化剂,提供了一种经济且环保的选择。Pd 0 / RGO的X射线衍射,X射线光电子能谱,扫描电子显微镜和透射电子显微镜图像表明,在还原的氧化石墨烯的薄片结构上产生了纳米级的Pd颗粒。在最佳条件下,最多可以制备44种结构不同的酮,并具有优异的收率。
