A boron filled hybrid nanotube and a method for producing and rendering boron filled hybrid nanotubes suitable for applications are provided. A mixture of a boron containing nanowire producing compound and catalysts is prepared and ground for a predetermined time period. The ground mixture is subjected to a vapor deposition process including passing an inert gas over the ground mixture after adding a nanotube producing compound to the ground mixture or after passing a reactant gas on the ground mixture in a reactor at a configurable reaction temperature and a configurable reaction pressure for a configurable reaction time to produce the boron filled hybrid nanotubes with enhanced mechanical, thermal and electrical properties. Each boron filled hybrid nanotube includes one or more boron based nanowires embedded within one or more single walled or multi-walled nanotubes. The boron filled hybrid nanotubes are further purified and functionalized using acids, and/or bases, and/or surfactants.
