New Palladium/Copper Precursors for Palladium/Copper/Polyvinylpyrrolidone Colloid
This research focuses on the use of colloids for the catalytic reduction of nitrite or nitrate to nitrogen for water decontamination. A new palladium/copper precursor for palladium/copper/polyvinylpyrrolidone colloid was made with palladium acetate [Pd3(OOCMe)6] and cupric acetate [Cu(OOCMe)2 ยท H2O] reacted in a 2:1 ratio. Our experiment consists of combining a Pd2Cu precursor (Kozitsyna et al., 2006) with the PVP, at reflux, in order to form the new colloid that will be used for the reduction. Results demonstrate that colloids prepared from the individual acetates are more effective because they have a higher reaction rate. Also, the reaction depends on the quantity of Cu and the results vary due to its loss during the preparation of the Pd2Cu precursor.
