General description
Molybdenum(IV) oxide (MoO2) is a transition metal oxide with good electrical conductivity due to the presence of delocalized electrons in its valence band. It is traditionally prepared by reducing MoO3 in dry hydrogen in the temperature range of 450-550°C.
Application
MoO2 can be used in a variety of energy based applications such as an anode material in rechargeable lithium batteries and fuel flexible solid oxide fuel cells. It can also be used as a catalyst in hydrogen reforming processes.
