Effects of Interaction between PAMAM and Polyoxometalates on Catalytic Performance for Oxidation of Isobutyraldehyde

Abstract:

G1.0 (Generation1.), G2.0, G3.0, G4.0 polyamidoamine (PAMAM) dendrimers-supported Na₅Co^II(H₂O)PW₁₁O₃₉ (PW11Co) were prepared by co-precipitation method. They were characterized by UV-Vis, XPS, XRD, and TEM. It is suggested that as the generation of the PAMAM dendrimers increased, the interaction between PW11Co and PAMAM dendrimer enhanced and the particle size of PW11Co decreased. The catalytic activities for the oxidation of isobutyraldehyde (IBA) to isobutyric acid (IBAc) by PW11Co-PAMAM(G1.0, G2.0, G3.0, G4.0) were examined.
