✦ Synopsis

A new type of functional fibre with high reducing ability toward Au 3+ was prepared by heat treatment of polyacrylonitrile precursor fibre in inert atmosphere. Both X-ray photoelectron spectroscopy and wide angle X-ray diffraction measurements showed that Au 3+ was nearly completely reduced to Au ° on the surface of the fibre after impregnation in AuC13"HC1 solution at room temperature. At the same time, the fibre was oxidized.
