在无水乙醇和乙酰丙酮混合溶液中,电解Ti金属制得前驱体Ti(OCH2CH3)(4-y)(acac)y,再加入ZrCl4,将上述溶液直接水解、干燥后在450℃煅烧2h,粉体通过X射线衍射(XRD)分析表明:纳米TiO2-ZrO2粉体呈单分散结构。通过凝胶涂抹、煅烧得到高活性的Ti/nanoTiO2-ZrO2修饰电极,电子透射显微镜(TEM)测试表明,颗粒平均尺寸为30～40nm。通过循环伏安研究发现,Ti/nanoTiO2-ZrO2电极对葡萄糖氧化具有高催化活性。
Ti (OCH2CH3) (4-y) (acac) y was prepared by electrolysis of Ti metal in a mixed solution of absolute ethanol and acetylacetone. ZrCl4 was added to the solution. The solution was directly hydrolyzed and dried at 450 ℃ for 2h. X-ray diffraction (XRD) analysis of the powder showed that the nano-TiO2-ZrO2 powder was monodispersed. The highly active Ti / nanoTiO2-ZrO2 modified electrode was obtained by gel coating and calcination. The transmission electron microscopy (TEM) results showed that the average particle size was 30 ~ 40nm. Cyclic voltammetry study found that Ti / nanoTiO2-ZrO2 electrode has high catalytic activity for glucose oxidation.
