▎ 摘　　要

Catalytic properties of thermally reduced (TRGO) and nitrogen-doped thermally reduced (N-TRGO) graphene oxides in acetylene hydrogenation in the temperature range of 50-400 degrees C were studied. The N-TRGO and TRGO materials were characterized by transmission and scanning electron microscopy, X-ray diffraction, Raman, infrared and X-ray photoelectron spectroscopies as well as elementary analysis techniques. The nitrogen incorporation in the graphene structure decreases the total activity for acetylene hydrogenation and the selectivity for ethylene. Oxygen-containing functional groups like ketone and hydroxyl groups may also contribute to catalytic activity. Methane, as a by-product, is produced due to acetylene hydrogenolysis that occurs on the structural defects. (C) 2019 Elsevier Ltd. All rights reserved.
