Study on reaction mechanism of dehydrogenation of magnesium hydride by in situ transmission electron microscopy
In situ observation on dehydrogenation of MgH 2 was performed by using transmission electron microscope (TEM). The dehydrogenation of MgH 2 with 1 mol % Nb 2 O 5 and formation of nanosized Mg particles were observed at 150 ° C . Nb 2 O 5 was not confirmed in diffraction patterns and TEM images pro...

was not confirmed in diffraction patterns and TEM images probably due to wide dispersion. On
MgH

, the high resolution TEM could recognize the dehydrogenation at the interface between
MgH
2
and
Nb

, proceeding with increasing temperature. This suggests that hydrogen atoms could diffuse from
MgH

phase to the interface between Mg and
Nb

, resulting in formation of hydrogen molecules at the interface.
