Abstract
We have prepared borocarbonitride (B x C y N z ) nanotubes of various compositions by a simple, template‐ and catalyst‐free procedure. The procedure involves heating borocarbonitride nanosheets at a high temperature (≈ 900 °C), having prepared the nanosheets by heating a mixture of boric acid and glycine at 475 °C. The nanotubes have been characterized by electron microscopy, X‐ray photoelectron spectroscopy and other techniques. Supercapacitor performance of the nanotube with high carbon content, BC 3 N, is noteworthy, with a specific capacitance of 164 F/g at a current density of 1.0 A/g.
