Highly Selective Hydrogenation of Acetylene Over Reduced Graphene Oxide Carbocatalyst

Abstract

Nitrogen-doped reduced graphene oxide (N-RGO) was synthesized by the treatment of graphene oxide with hydrazine. The obtained material was characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman , nitrogen adsorption-desorption isotherm, and XPS. The catalytic activity of N-RGO in acetylene, ethylene hydrogenation, and preferential acetylene hydrogenation in the ethylene excess was determined. In the acetylene hydrogenation, the selectivity of 97% for ethylene is achieved. A possibility of a complete conversion of acetylene to ethylene in the acetylene-ethylene mixture with ratio 1:9 is shown.
