在钨酸溶胶的制备中，H_2O_2、乙醇的加入能增强钨酸溶胶的稳定性，当H_2O_2与钨酸的摩尔比为1：2，乙醇与钨酸体积比为1：2时，溶胶的保存时间较长，成膜质量较好。

The microstructure and morphology are examined by SEM, XRD, EPMA, and the electrochemical performance is studied by potentiodynamic polarization and current efficiency. The results show that the alloy elements in the electrode coating prepared by the sol-gel process are well distributed, more sufficient to form solid solution and with higher current efficiency than by the traditional thermal decomposition process. The deactivation effect is due to the forming of unconductive TiO2 for the sol-gel process, but due to the dissolution of active composition for the thermal decomposition process.
