Description General description 4-Methoxybenzyl alcohol on condensation with the silanol groups of fumed silica nanoparticles yields modified silica nanoparticles. It undergoes catalytic photooxidation by flavin-zinc(II)-cyclen complex to yield the corresponding benzaldehyde. Application 4-Methoxybenzyl alcohol was used to study the photocatalytic oxidation of 4-methoxybenzyl alcohol to p-anisaldehyde. Packaging 5, 100, 500 g in glass bottle
