【摘要】 采用弱碱NH4HCO3控制pH软化学合成法,研制了TiO2纳米粒子.该法程序简单,条件易控,目标产品产率高,对环境无污染.为TiO2纳米粒子的制备提供了一种具有实用价值的新方法.红外光谱(IR)对TiO2产品进行了定性分析,产品的IR波形,特征吸收峰强度与标准产品完全一致.扫描电子显微镜(TEM)测试了TiO2纳米粒径在70mm左右,松散无团聚.讨论了TiO2纳米粒子独特性质基础上的应用.更多还原

【Abstract】 TiO₂ nano-particle is developed by using the weak base NH₄HCO₃ to control pH soft chemical synthesis method.This method to develop TiO₂ nano-particle is easy to control,practical,valuable,efficient and without pollution.IR is used to analyze TiO₂ products only to find that they is up to the standard.TEM is used to test the TiO₂ nano-particle diameter,which is around 70 mm. The application of TiO₂ nano-particle is also discussed.更多还原
