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 …

Titanium alkoxides were prepared by anodic dissolution of metallic titanium in absolute ethanol in the presence of HN(C 2H 5) 2·HCl (electro_conductive additives).The solution was directly hydrolyzed to prepare nanocrystalline of TiO 2 (about 10nm)by a sol_gel process.The precursor gels was calcined at T =450 ℃ and 720 ℃for 30 min,and nanocrystalline of TiO 2 (anatase) with high textural and thermal stability was obtained.FTIR,XRD,TEM,were used to characterize the structure of titanium alkoxides and nanocrystalline of TiO 2.The characteristics of nanocrystalline of TiO 2 was depended on the properties of titanium alkoxides.The Ti(OEt) 4 as a source of titanium yielded the …
