Abstract
Starting from waste polytetrafluoroethylene (PTFE), metal oxides (TiO2, V2O5, Nb2O5, and MoO3) and metal sodium, several nanocrystalline transition metal carbides (TiC, VC, NbC, and Mo2C) have been prepared through a thermal reduction route in an autoclave at 600 °C. It is found that the obtained NbC nanocrystallines have a superconducting transition temperature at 11.6 K.
► NbC can be prepared from metal sodium, Nb2O5 and waste polytetrafluoroethylene. ► The obtained NbC have a superconducting transition temperature at 11.6 K. ► This route has been extended for the preparation of carbides (TiC, VC, Mo2C).
