摘要：

Tungsten oxynitride nanowires were generated by the reaction of ammonia with ultra- thin tungsten oxide nanowires which were themselves prepared by a simple solvo- thermal treatment of tungsten chloride in a cyclohexanol solvent. The resulting tungsten oxynitride nanowires exhibited a high specific surface area of 221 m(2) g(-1), even exceeding that of 151 m(2) g(-1) for the bundled and ultra- thin tungsten oxide nanowire precursor. The observed weak, temperature- independent paramagnetism indicates that the tungsten oxynitride nanowires are metallic, but no superconducting transition was observed above 2 K.
