Preparation, Structures Nano-TiO_2 Particles, and the properties of TiH_2 Coated with Nano-TiO_2

摘要

The surface of Titanium Hydride (TIH_2) is coated by Nano-Titanium Doxide (TiO_2) particles prepared in both of methods of hydrolysis eadcion 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 temeprautre. 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.
