| Abstract: | A series of Keggin‐type polyoxometallates, M3(PW12O40)2 M=Ni, Zn, Co, Mn, Cu], FePW12O40, Ni3(PMo12O40)2 and Ni2SiW12O40, were prepared and used as catalysts for selective oxidation of benzyl alcohol into benzaldehyde with H2O2 as an oxidant under solvent‐free condition. Ni3(PW12O40)2·26H2O afforded high catalytic activity with TON of 550.6 mol/(mol cat.) and 87.3% selectivity. However, this catalyst can be easily recovered and reused. |
