NOVELTY - Use of fullerene as cuprous stabilizer, is claimed. USE - The fullerene is useful as cuprous stabilizer in preparation of fullerene-stabilized cuprous functional material for catalysts, energy storage batteries, sensors or preparation of bactericidal and antiviral medicine (all claimed). ADVANTAGE - The fullerene: is cage-shaped carbon molecule that can act as unique electron pool that accepts or donates electrons; controls the valence state of copper in close contact with it by absorbing a single electron from zero-valent copper or donating a single electron to divalent copper; makes the transition of cuprous to copper(0) or copper(II) tend to passivate and stabilize the valence state of copper to positive monovalent; stabilizes the content of cuprous in the material; and ensures the activity of the cuprous functional material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) fullerene-stabilized cuprous functional material includes inorganic carrier, fullerenes and nano copper supported on the surface of the inorganic carrier, where the nano copper is composed of cuprous; and (2) preparing fullerene-stabilized cuprous functional material, comprising calcining fullerene-stabilized cuprous functional material precursor and reducing to obtain fullerene-stabilized cuprous functional material, where the fullerene-stabilized cuprous functional material precursor is fullerene-inorganic carrier-copper precipitate or fullerene-inorganic carrier-copper salt ball milling powder.
