摘要
The surface of Titanium Hydride (TiH 2) is coated by Nano Titanium Dioxide (TiO 2) particles prepared in both of methods of hydrolysis reaction of Ti(OC 4H 9) 4 and base precipitation reaction of Ti(SO 4) 2. TiH 2 coated with nano TiO 2 particles, in which there is an oxidation film on its surface, shown in the experiments, will obviously achieve good effects on releasing hydrogen slowly in high temperature. There are different structures and properties of TiH 2 coated by nano TiO 2 particles prepared in different ways in high temperature, which can influence on releasing hydrogen.
用金属醇盐法和金属盐碱性沉淀法制备的ＴｉＯ２ 纳米粒子包裹于释氢剂ＴｉＨ２ 外表．实验表明，经包裹后的氢化钛，具有明显的高温缓释效果．不同方法制备的二氧化钛包裹物，在高温下有不同的结构和性能，影响释氢剂在高温下的释氢．
