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 CH 3COCH 2COCH 3.The Ti_based nanocrystalline TiO 2 Film electrode (Ti/nano_TiO 2) was prepared by sol_gel method.By TEM,SEM and XRD,it has been shown that the anatase particle of TiO 2 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_TiO 2 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).
