A series of Keggin‐type polyoxometallates, M 3 (PW 12 O 40 ) 2 [M=Ni, Zn, Co, Mn, Cu], FePW 12 O 40 , Ni 3 (PMo 12 O 40 ) 2 and Ni 2 SiW 12 O 40 , were prepared and used as catalysts for selective oxidation of benzyl alcohol into benzaldehyde with H 2 O 2 as an oxidant under solvent‐free condition. Ni 3 (PW 12 O 40 ) 2 ·26H 2 O 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.
