OH radical and the photo generated holes are essential to the oxidation of benzyl alcohol into benzaldehyde with TiO2.

Efficient trapping of electrons accelerates the formation of benzaldehyde.

Compared with radical dot" data-inlimg="/entities/rad" src="/sd/grey_pxl.gif" class="glyphImg imgLazyJSB">
OH radical, the photo generated holes prefer to capture an H atom from benzyl alcohol.
