    • Methods for manufacturing carbon nanostructures include 1) forming intermediate carbon nanostructures by polymerizing a carbon precursor in the presence of templating nanoparticles, 2) carbonizing the intermediate carbon nanostructures to form an intermediate composite nanostructure, and 3) removing the templating nanoparticles from the intermediate composite nanostructure to form carbon nanorings. The carbon nanorings manufactured using the foregoing steps have one or more carbon layers forming a wall that defines a generally annular nanostructure having a hole. The length of the nanoring is less than or about equal to the outer diameter thereof. The carbon nanostructures are well-suited for use as a fuel cell catalyst support. The carbon nanostructures exhibit high surface area, high porosity, high graphitization, and facilitate mass transfer and electron transfer in fuel cell reactions. Carbon nanorings manufactured according to the present invention can be used as a substitute for more expensive and likely more fragile carbon nanotubes.
    • 制造碳纳米结构的方法包括:1)在模板纳米颗粒存在下,通过聚合碳前体形成中间碳纳米结构,2)碳化中间碳纳米结构以形成中间复合纳米结构,和3)从中间复合纳米结构中除去模板纳米颗粒 以形成碳纳米管。 使用上述步骤制造的碳纳米管具有形成壁的一个或多个碳层,所述壁限定具有孔的大致环形的纳米结构。 纳米的长度小于或等于其外径。 碳纳米结构非常适合用作燃料电池催化剂载体。 碳纳米结构表现出高表面积,高孔隙率,高石墨化,并促进燃料电池反应中的传质和电子传递。 根据本发明制造的碳纳米管可以用作更昂贵和可能更脆弱的碳纳米管的替代物。
