Abstract:

The precursor Ti（OCH₂CH₃）_（4-y）（acac）_y was synthesized by electrolysis of titanium and in absolute ethanol and acetyl-acetone solution.0.5 g ZrCl4 was added into the above.Nano-crystalline TiO₂-ZrO₂ powder was prepared by directs sol-gel method from the precursor and then calcined for 2 h at 400℃. XRD and TEM results showed that the nano-TiO₂-ZrO₂ of 30—40 nm was obtained.The highly active Ti/nanoTiO₂-ZrO₂ modified electrode was prepared by using daubing and drying.The results of cyclic voltammetry showed that Ti/nanoTiO2-ZrO2 modified electrode as anode exhibited high electrocatalytic activity for electro-oxidation of glucose.

摘要：

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2 h，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
