The precursor Ti(OEt)4 was prepared by anodic dissolution of Ti in absolute ethanol and directly hydrolyzed to give nanocrystalline TiO2 film on titanium electrode (Ti/nano-TiO2) by a sol-gel process.The nanocrystalline TiO2-Pt modified titanium (Ti/nano-TiO2-Pt) electrode was prepared by electrodeposition of Pt on nanocrystalline TiO2 film.Electrocatalytic activity of the Ti/nano-TiO2-Pt electrode for oxidation of Mn2+ to Mn3+ and synthesis of glyceraldehydes were investigated by cyclic voltammetry and indirect electro-oxidation methods.Mn3+ could be regenerated by electrolysis at Ti/nano-TiO2-Pt anode in heterogeneous MnSO4/H2SO4 medium with current efficiency over 90%.Glyceraldehyde was prepared in yield of 91% by the proposed method.
