Template synthesis of B-doped graphene-like carbon nanomaterial from phenylboronic acid

Abstract

A template method for synthesis of B-doped graphene-like carbon nanomaterial (B-graphene-like carbon) with high surface area has been developed. In this method, magnesium oxide is used as a template where a carbon layer doped with boron atoms is deposited. Magnesium oxide carbonization was performed in an autoclave at 600 °C and 5 atm pressure using phenylboronic acid (FBA) dissolved in an ethanol-acetone mixture. Then, magnesium oxide from the С—B/MgO composite was dissolved in hydrochloric acid. The obtained B- graphene-like carbon was studied by IR spectroscopy, electron microscopy, XPS methods and quantum chemical calculations. B-graphene-like carbon contains 3–6 carbon layers and 0.2 wt% B. Structure of carbon net with embedded boron fragment has been proposed as the result of performed studies.
