Abstract
Charge state of Zr atoms in ZrV2 intermetallic compound and its hydride ZrV2H4 has been studied using the X-ray absorption spectroscopy (XAS) method. Thermal stability of the hydride has been investigated employing the thermodesorption spectroscopy (TDS) method. It has been established the positive charge on Zr ions in ZrV2H4 hydride (i.e., the “transfer” of electronic charge from Zr atoms during formation of the hydride), and this fact indicates the presence of ionic component of metal-hydrogen bonds in the hydride. The conclusion about the existence of correlation between observed increasing thermal stability of ZrV2H4 hydride and ionic component of its metal-hydrogen bonds has been made.
