A paired electrosynthesis of zinc gluconate and succinic acid using novel nano-electrodes was studied. A Ti/nanoTiO2 electrode and a nanoTiO2 film loaded Pt nanoparticle electrode (Ti/nanoTiO2-Pt) were prepared by a sol-gel method and an electrochemical deposition technique. The results of cyclic voltammetry showed that the Ti/nanoTiO2-Pt electrode as anode and the Ti/nanoTiO2 electrode as cathode exhibited high electrocatalytic activity for electro-oxidation of glucose and electro-reduction of maleic acid respectively. According to the orthogonal experiment, the optimum conditions obtained were as follows: anodic and cathodic current density at 1.2 and 3.0 A•dm－2 respectively, 0.4 mol•L－1 glucose and 0.6 mol•L－1 NaBr in anodic electrolyte, 0.6 mol•L－1 maleic acid and 0.2 mol•L－1 NaCl in cathodal electrolyte, and the temperature at 50 ℃. Total current efficiency attained to 170%.
