Carbon nanocoils with nanometer‐thick graphitic fibers (see picture) were synthesized by the simple heat treatment of nanocomposites of a carbon precursor, silica, and a transition‐metal salt. The carbon nanocoils exhibited a high surface area and a highly graphitized structure. The nanocoils were then successfully applied as catalyst supports for direct methanol fuel cell electrodes.
