Abstract
The reaction of fullerene C60, single- and multi-walled carbon nanotubes (SWNTs and MWNTs, respectively), as well as a mixture of these carbon nanomaterials with 8–10 wt% of ammonium chloride (reaction promoter) with ammonia as a source of hydrogen and nitrogen, at an initial ammonium pressure of 0.6–0.8 MPa in the temperature range 20–550°C was studied. The reaction at 450°C is accompanied by hydrogenation and nitrogenation of the fullerite matrix, and at 500°C decomposition of the fullerene carcass occurs. Physicochemical properties of the hydride-nitride phases formed by the reaction were studied. Single- and multiwalled nanotubes were shown to be stable in an ammonium medium at 20–450°C, while at 500°C their ends are opened.
