Аннотация:Thin-film nanocrystalline hematite electrodes were fabricated by electrochemical depositionand loaded with electrodeposited zinc oxide in various amounts. Under visible light illumination,these electrodes demonstrate high activity in the photoelectrochemical degradation of methanol,ethylene glycol and, in particular, glycerol. Results of intensity-modulated photocurrent spectroscopyshow that the photoelectrocatalysis efficiency is explained by the suppression of the electron–holepair recombination and an increase in the rate of photo-induced charge transfer. Thus, zinc oxide canbe considered an effective modifying additive for hematite photoanodes.
