一步水热法制备核壳型纳米粉体

Preparation of core-shell nano-material by one-step hydrothermal method

液相法制备核壳纳米粉体具有反应温度低、设备简单、能耗少的优点,而一步水热法在液相法中具有其它方法无法比拟的优越性。重点讨论了一步水热法制备核壳纳米粉体的工艺流程和机理。

The importance of surface modification and modification methods were briefly stated. And the preparation of core-shell nano-material is an important technique. Preparation of core-shell nano-material in liquid has advantages of low reaction temperature, simple equipment and less waste of energy. But, one-step hydrothermal method is more excellent in the preparation of core-shell nano-material. Therefore, the process and principle of one-step hydrothermal method was discussed.
