【摘要】用溶胶-凝胶法制备了多孔TiO₂纳米薄膜修饰的镍基电极。用STM观察了TiO₂纳米薄膜的表面形貌。由STM知,随烧结温度升高和PEG（聚乙二醇）含量增加,TiO₂纳米薄膜表面孔穴的数量增加,孔径增大。更多还原

【Abstract】 Porous nanosized TiO2 films are prepared on nickel by sol-gel process,the STM morphology ofthe nanosized TiO2 films are given-Through STM,we know that the pore quantity and diameter of nanosized TiO2 film increase with the increment of sintering temperature and the content of PEG.更多还原
