“…One‐dimensional (1D) nanostructures such as nanowires (NWs), nanorods, and nanotubes have attracted tremendous attention because of their size‐dependent optical, electronic, mechanical, and sensing properties, opening up unprecedented opportunities to construct nanodevices with new functionalities which could be achieved at the micro/macro scales 16–19. Although TaC powders and whiskers have been prepared by carbothermal reduction, thermal plasma, solvothermal, sol‐gel, microwave heating, alkalide reduction, self propagating high temperature synthesis, and high frequency induction heated sintering,7–13 there are only few corresponding routes to synthesizing 1D TaC nanostructures. Fukunaga et al prepared TaC nanorods via carbon nanotubes confined vapor‐solid reaction 14.…”
