Abstract
The potentiostatic electrosynthesis of Ti(EtO)4 was studied by anodic dissolution of metal titanium(TA1) in solution of 0.005 mol·L-1 (EtO)4NBr in the ethanol (AR) in the presence negligible CH3COCH2COCH3. The Ti-based nanocrystalline TiO2 Film electrode (Ti/nano-TiO2) was prepared by sol-gel method. By TEM, SEM and XRD, it has been shown that the anatase particle of TiO2 was 10～35 nm in diameter and the film was 0.5 μm in thickness. The nanocrystalline film was composed of a three-diminsional network of interconnected particles. Reodx behavior and electrocatalytic activities of the Ti/nano-TiO2 electrode were investigated by cyclic voltammetry (CV) from oxalic acid and nitrobenzene to glyoxalic acid and p-aminionphenol. The Ti(Ⅳ)/Ti(Ⅲ) redox system, as a medium, shows highly electrocatalytic activities and stable characteristic to indirect electroreduction of organic compounds (e.g.:oxalic acid and nitrobenzene).
