Infrared Studies on Bimetallic Copper/Nickel Catalysts Supported on Zirconia and Ceria/Zirconia
ABSTRACT Infrared spectroscopy has been employed for a detailed characterization of ZrO2 and CeO2/ZrO2 supported nickel and copper/nickel catalysts to be utilized for methane decomposition. Adsorption of CO at 303 K was performed in order to determine the surface composition and accessible adsorption sites. Alloy formation occurred during reduction, as indicated by a red-shift of the vibrationa...
متن کاملEffect of Nickel Particle Size on Alumina Supported Nickel Catalysts for p-Nitrophenol Hydrogenation
The catalytic hydrogenation of p-nitrophenol to p-aminophenol was investigated over alumina supported nickel catalysts prepared by impregnation reduction method and mechanical mixing method. The catalysts were characterized by XRD and FESEM. The results show that the nickel particle diameter of alumina supported nickel prepared by impregnation reduction method (denoted as Ni/Al2O3) is slightly ...
متن کاملTotal Oxidation of Naphthalene with Zirconia-Supported Cobalt, Copper and Nickel Catalysts
ZrO2·nH2O (hydrogel) impregnated with transition metals (Cu, Co, and Ni) was studied in this work as a precursor for the synthesis of CuO/ZrO2 (CuZ), CoOx/ZrO2 (CoZ), and NiO/ZrO2 (NiZ) catalysts, employed in the naphthalene oxidation reaction. Fresh and catalytically used materials were characterized by different physicochemical techniques, to compare the bulk and surface behavior, with partic...
متن کاملStructural and Catalytic Properties of Model Supported Nickel Catalysts
published in Aduonce ACS Abstracts, January 1, 1994. 0022-36S4/94/2098-124S%04.S0/0 nation at present. Martini2 and Goodmani3 have suggested that the activity of different crystal planes toward hydrogenolysis is responsible for the observed variations in activity with metal particle size. Single-crystal surface science studies have shown these structure-sensitive reactions to proceed more rapid...
متن کاملThe Kinetics of Methanation on Nickel Catalysts
An empirical rate equation was obtained for the methanation kinetics catalyzed by MCR-2X, a commercial catalyst prepared by Haldor-Topsoe. The studies were carried out in a fixed-bed reactor under differential conditions, and in a gradientless recycle reactor (Berry) over a range of total pressures, reactant concentractions (H2/CO ratios), and temperatures. The kinetics of methanation were foun...
