Determination of surface grafene-boron nitride

Abstract

Purified powder of t-BN_g for attestation its porous structure have used. The material have described as homogenous, micro-mesoporous (monodisperse) with a narrow distribution slit-like pores still in the range of 3,53—4,12 nm, which accounts for about 55% of the volume and 60% of the surface mesoporous. The area of the outer surface of mesoporous is 28,3 m²/g (t-method), internal — 141 m²/g (method BJH). Powder Nanodimension t-BN_g urea synthesis require to additional cleaning of impurities polycondensed planar boron nitride particles of oxygen boron nitride. Oxygen boron nitride in the form of refined sublimate as white powder was isolated from the washed and dried example t-BN_g at Temperature 540 K and Pressure ~ 1,0—5,0 Pa. Sublimate have identified in assuming as a six-membered heterocycles dimer with molecular formula H(OH)[(BON)₂](OH)H.
