利用氧化石墨（GO）作为一种新型的主体材料的Pd纳米粒子的控制微晶尺寸。将Pd纳米粒子从稳定的Pd溶胶中固定在GO中，形成亲有机的Pd-GO，这是一种层状结构的材料，其通过ICP-AES，XRD和TEM进行表征。Pd-GO是一种高活性、高立体选择性的催化剂，在温和条件下进行了液相炔加氢反应。
Graphite oxide (GO) was utilized as a novel host material for Pd nanoparticles of controlled crystallite size. Immobilization of the Pd nanoparticles from a stable Pd sol in GO resulted in the formation of organophilic Pd–GO, a layer-structured material, which was characterized by ICP-AES, XRD and TEM. Pd–GO proved to be a highly active and stereoselective catalyst in liquid-phase alkyne hydrogenations under mild conditions.
