The synthesis of novel nanoparticles is of general importance for the development of efficient heterogeneous catalysts. Herein, the preparation of carbon‐supported nickel‐based nanoparticles (NPs), modified by nitrogen‐doped graphene layers, is reported for the first time. The resulting materials were characterized in detail by TEM, X‐ray photoelectron spectroscopy (XPS), XRD, elemental analysis (EA)
新型纳米颗粒的合成对于开发有效的非均相催化剂具有普遍的重要性。本文首次报道了碳掺杂的镍基纳米颗粒(NPs)的制备,该纳米颗粒被氮掺杂的石墨烯层改性。通过TEM,X射线光电子能谱(XPS),XRD,元素分析(EA),电子顺磁共振(EPR),程序升温还原(TPR),BET和拉曼分析对所得材料进行了详细表征。初步的催化测试表明这类化合物在加氢反应中的潜力。
