Boron-doped nanoporous carbons as promising materials for supercapacitors and hydrogen storage

Abstract

Boron-doped carbon nanostructures were obtained via template and bulk synthesis from sucrose in the presence of boric acid. Synthesized B-containing mesoporous materials are characterized by high spatial ordering, developed surface (up to 870 m2/g), and porosity (up to 1.2 cm3/g). The obtained B-doped microporous materials exhibit high interfacial capacitance (up to 0.36 F/m2), which is higher than the available literature data and enables the use of synthesized samples as materials of supercapacitors. The capacity of electric double layer up to 300 F/g using sulfuric acid as the electrolyte was accumulated on microporous B-doped carbons.
