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...

Synthesis of MWCNTs Using Monometallic and Bimetallic Combinations of Fe, Co and Ni Catalysts Supported on Nanometric SiC via TCVD

Nanometric Carbid Silicon (SiC) supported monometallic and bimetallic catalysts containing Fe, Co, Ni transition metals were prepared by wet impregnation method. Multiwall carbon nanotubes (MWCNTs) were synthesized over the prepared catalysts from catalytic decomposition of acetylene at 850°C by thermal chemical vapor deposition (TCVD) technique. The synthesized nanomaterials (catalysts and CNT...

Hydrodeoxygenation of Acetic Acid Using Monometallic and Bimetallic Catalysts Supported on Carbon

Heterogeneous catalytic hydrodeoxygenation (HDO) of biomass-derived feeds is a deoxygenation process that is of highly interest. Carboxylic acids are one of the main components of bio-oils and acetic acid (AA) is one of the most abundant of these carboxylic acids. This acid is rich in oxygen, therefore there is a lot of research for to produce fuel and other valuable chemicals such as ethanol. ...
