| 摘 要： | 使用新颖的纳米结构电极成对电合成葡萄糖酸锌和丁二酸.采用溶胶-凝胶法制备Ti基纳米TiO2(Ti/nanoTiO2)电极,同时采用电沉积法制备Ti基纳米TiO2-Pt(Ti/nanoTiO2-Pt)修饰电极.通过循环伏安研究发现,Ti/nanoTiO2-Pt电极对葡萄糖氧化及Ti/nanoTiO2电极对马来酸还原均具有高催化活性.以Ti/nanoTiO2-Pt电极为阳极、Ti/nanoTiO2电极为阴极,通过正交实验得到成对电合成葡萄糖酸锌和丁二酸的优化条件为:阳极和阴极电流密度分别为1.2A·dm-2和3.0A·dm-2,阳极液为0.4mol·L-1葡萄糖+0.6mol·L-1NaBr,阴极液为0.6mol·L-1马来酸+0.2mol·L-1NaCl,温度50℃.成对电合成的总电流效率达到170%.

| Abstract: | 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 res... |
