We show a facile one‐step surfactant‐assisted solution process to fabricate selenium/carbon (Se/C) coaxial core–shell submicrowires and their transformation into carbon submicrotubes by dissolution of the Se cores at ambient temperature. The formation process of the Se/C core–shell submicrowires was investigated. The results of the investigation and further experiments confirm that the thickness of the carbon shell could be tailored by controlling the experimental conditions. The as‐synthesized Se/C core–shell submicrowires and the carbon submicrotubes are potentially useful in applications such as in nanodevices or biomedicine.
