Effect of the Method of Production of Reduced Graphene Oxide on its Catalytic Activity in the Hydrogenation of Ethylene

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.
