“…7 The absorption of hydrogen or the formation of TiH 2 is probably needed to produce the porous TiO 2 layer in the alkaline solution. The porous TiO 2 is produced from TiH 2 according to the following anodic reaction 11 TiH 2 ϩ H 2 O → TiO 2 ϩ 6H ϩ ϩ 6e Ϫ ͓4͔ However, we cannot explain the structural formation mechanism that led to the porous structure by the dissolution of TiH 2 ; therefore, further detailed investigations are necessary.…”

The formation of a porous TiO 2 layer by immersing Ti in 5 M NaOH at 303 K was investigated using electrochemical measurements, a scanning electron microscope, and grazing incident X-ray diffraction. The porous layer was readily obtained in the case of the presence of titanium hydride (TiH 2 ) on the surface before immersion. The crystalline structure of the porous layer is composed of a mixture of the rutile and anatase type TiO 2 . The porous layer is hard to produce without the presence of TiH 2 . The TiH 2 is directly changed to TiO 2 by a dissolution reaction in alkaline solution. The presence of TiH 2 on the surface is an important factor for the preparation of the porous TiO 2 layer.

“…This data was used as a reference for hydrogen absorption property of the material, and the effect of deformation on the property is measured and compared at three charging time. At the start of charging, the amount of hydrogen increases linearly with absorption time, then the relationship becomes parabolic due to hydride formation [18,19]. In the as-received material, the linear relation at the early stage is not apparent.…”
