Nanostructured Carbon-Doped BN for CO₂ Capture Applications.

ABSTRACT: Carbon-doped boron nitride (denoted by BN/C) was prepared through the pyrolysis at 1100 °C of a nanostructured mixture of an alkyl amine borane adduct and ammonia borane. The alkyl amine borane adduct acts as a soft template to obtain nanospheres. This bottom-up approach for the synthesis of nanostructured BN/C is relatively simple and compelling. It allows the structure obtained during the emulsion process to be kept. The final BN/C materials are microporous, with interconnected pores in the nanometer range (0.8 nm), a large specific surface area of up to 767 m²·g^-1 and a pore volume of 0.32 cm³·g^-1. The gas sorption studied with CO₂ demonstrated an appealing uptake of 3.43 mmol·g^-1 at 0 °C, a high CO₂/N₂
