英文摘要: Cobalt carbide (CO2C) samples were prepared by carburizing Co with CO at 473 K for in excess of 400 h and were characterized by X-ray diffraction, transmission electron microscopy, CO temperature-programmed reduction, CO temperature-programmed desorption (CO-TPD), and CO temperature-programmed surface reaction. The prepared CO2C samples were composed of bulk Co2C with a surface CoO passivation layer. The passivation layer could be removed by reaction with CO at 477 K. CO desorbing at low temperature in CO-TPD experiments likely originated from chemisorbed CO. CO desorbing at high temperature was likely due to residual CO within the CO2C crystal lattice. CO adsorbed on Co2C reacted with H-2 to form alcohol. (C) 2013, Dalian Institute of Chemical Physics, Chinese Academy of Sciences. Published by Elsevier B.V. All rights reserved.
