An efficient and selective photochemical method for the oxidation of benzylic alcohols has been achieved using phosphotungstic acid supported on imidazole functionalized silica coated cobalt ferrite nanoparticles as a magnetically photocatalyst in acetonitrile with O₂. The photocatalyst has been reused several times, without observable loss of activity and selectivity. Results showed this heterogeneous photocatalyst is more active than the unsupported H₃PW₁₂O₄₀
