文摘

Rare earth metal ion-exchanged heteropolytungstate shows high catalytic activity for oxidation of benzyl alcohol. Good catalytic activity due to Brønsted-Lewis acid synergy of catalyst. Acidic properties of rare earth exchanged heteropolytungstate catalysts probed by the 31P-TMPO MAS NMR approach. Experimental variables during oxidation over Ce1/3H2PW12O40 catalyst optimized by RSM.
