The catalytic properties of N-doped hydrazine-reduced graphene oxide (N-RGO) and thermally reduced graphene oxide (TRGO) in the hydrogenation of ethylene by molecular hydrogen were studied. Samples of the TRGO and N-RGO were characterized by transmission and scanning electron microscopy, X-ray diffraction, and Raman and X-ray photoelectron spectroscopy. It was shown that decrease of the oxygen content in the reduced graphene oxide increases its catalytic activity.

还原氧化石墨烯的制备方法对其催化乙烯加氢活性的影响

研究了N掺杂肼还原氧化石墨烯（N-RGO）和热还原氧化石墨烯（TRGO）在分子氢加氢乙烯中的催化性能。TRGO 和 N-RGO 的样品通过透射和扫描电子显微镜、X 射线衍射以及拉曼和 X 射线光电子能谱进行表征。结果表明，还原氧化石墨烯中氧含量的降低会增加其催化活性。
