High Temperature Partial Oxidation Reactions over Silver Catalysts
The exceptional catalytic activity of silver for a number of partial oxidation reactions has been known for nearly a century. Despite the wid espread use of silver in heterogeneous catalysis, there still remain unresolved questions about the mechanistic details of reaction. The ethylene epoxidation and formaldehyde synthesis reactions are the two industrially-relevant reactions which have recei...
متن کاملStudy on spinel supported gold catalysts for alcohol oxidation reactions
Gold had been regarded as an inactive metal in catalysis due to its inert chemical nature. However, it was found that when gold is prepared as nanoparticles, it can exhibit surprisingly high activity for various reactions, especially for oxidation reactions [1]. In order to obtain gold nanoparticles (AuNPs), support is commonly used, which can not only help to avoid agglomeration of AuNPs, but ...
متن کاملAscorbic acid and copper in linoleate oxidation. II. Ascorbic acid and copper as oxidation catalysts.
Both ascorbic acid and copper were strong prooxidants in the oxidation of linoleate in a buffered (pH 7.0) aqueous dispersion at 37 degrees C. Minimum concentrations at which catalytic activity was detected were 1.3 x 10(-7) m for copper and 1.8 x 10(-6) m for ascorbic acid. For concentrations up to 10(-3) m, the increase in rate of oxidation with increase in concentration of catalyst was great...
متن کاملAscorbic acid and copper in linoleate oxidation. 11. Ascorbic acid and copper as oxidation catalysts
Both ascorbic acid and copper were strong prooxidants in the oxidation of linoleate in a buffered (pH 7.0) aqueous dispersion at 37OC. Minimum concentrations at which catalytic activity was detected were 1.3 X 10-7 M for coppcr and 1.8 X 10-6 M for ascorbic acid. For concentrations up to lop3 M, the increase in rate of oxidation with increase in concentration of catalyst was greater for ascorbi...
متن کاملPreparation of ultra low loaded Au catalysts for oxidation reactions.
Cyanide leaching was used to obtain Au/SiO2 catalysts with very low gold loadings. A number of catalysts with a nominal 5 wt% target loading were prepared using impregnation and deposition precipitation techniques and these were found to be active catalysts for the solvent-free aerobic oxidation of benzyl alcohol. Exposure of these catalysts to a basic solution of NaCN for 10 min leached gold f...
