Molybdenum oxoanions as dispersing agents in the preparation of Pd/C catalysts for the selective oxidation of glyoxal

Catalysts Pd/C were prepared in the presence of Mo oxoanions. The size of Mo precursor and the electrostatic interactions with the Pd precursor during the synthesis were found to be responsible for high Pd dispersions. These catalysts were very active for glyoxal oxidation into glyoxalic acid. © 2012 Springer Science+Business Media, LLC
