摘要： The preparation method according to the present disclosure is to easily prepare hexagonal molybdenum oxide (h-MoO3) having a nanorod shape even in a low temperature precipitation reaction at atmospheric pressure without applying hydrothermal synthesis under high temperature and high pressure conditions. The hexagonal molybdenum oxide (h-MoO3) nanorods prepared therefrom can be properly mixed with carbon-based conductive materials such as carbon nanofiber, and thus can be usefully used as an anode material for a pseudocapacitor.
