FAQs
  • What makes MoO₂ unique among metal oxides?
    加 Created with Sketch.
    形状 Created with Sketch.
    Its most distinctive feature is its unusually high electrical conductivity, which is more like a metal than a typical insulating oxide . This, combined with its high chemical stability and melting point, makes it valuable for advanced applications .
  • Is MoO₂ soluble in water or acids?
    加 Created with Sketch.
    形状 Created with Sketch.
    It is insoluble in water, hydrochloric acid (HCl), and alkalis. It is slightly soluble in hot, concentrated sulfuric acid and can be dissolved by oxidizing acids like nitric acid (HNO₃), which convert it to molybdenum trioxide (MoO₃) .
  • What are the primary applications of MoO₂?
    加 Created with Sketch.
    形状 Created with Sketch.
    MoO₂'s high conductivity and stable structure make it a key functional material in several cutting-edge fields:
    ·Energy Storage: A highly promising anode material for lithium-ion batteries due to its high capacity and stability during charging cycles.
    ·Catalysis: Used as a catalyst, particularly in reforming hydrocarbons.
    ·Electronics & Sensors: Used in conductive thin films, field emission devices, and as a sensitive material for gas sensors.
    ·Emerging Research: Explored in areas like photothermal cancer therapy and as an antibacterial agent due to its low toxicity and unique properties.
  • How should MoO₂ be stored?
    加 Created with Sketch.
    形状 Created with Sketch.
    MoO₂ should be stored in a cool, dry, and well-ventilated place, sealed under an inert atmosphere (like argon or nitrogen) to prevent slow oxidation over time.
