However, carbon dioxide can utilized for the production of methane in a hydrogenation reaction. The hydrogenation of carbon dioxide requires the presence of catalysts in order to overcome the large kinetic barrier. In this study, paltinum doped nickel oxide has been synthesized by the powder mixing method. The catalytic activity of the prepared catalysts was monitored using a fixed-bed reactor which is connected to Fourier transform infrared (FTIR) instrument for the hydrogenation reaction. The catalytic activity study showed that the Pt: Ni of atomic ratio 0.1:1 and calcined at 600 C for 3 hours was capable of converting 89% carbon dioxide at reaction temperature of 400 C. The percentage of methane formation was also 89% at reaction temperature of 400 C. The x-ray diffraction (XRD) analysis indicated the presence of nickel oxide cubic (NiO cubic( phase as the active phasefor the particular reaction. The scanning electron microscope (SEM) analysis revealed that the catalyst particle size was in the range of 89-190nm of slightly definite cubical shape. 2010-08-19T07:22:59Z 2010-08-19T07:22:59Z 2010 Article World Applied Sciences Journal, vol.8(4), 2010, pages 490-495 1818-4952 http://www.idosi.org/wasj/wasj8(4)10/16.pdf http://hdl.handle.net/123456789/8857 en IDOSI Publications |
