Abstract
Using a combination of methods including low-temperature nitrogen adsorption, scanning electron microscopy, X-ray diffraction, and others, the particle size distribution and morphology of amorphous boron, vanadium pentoxide, and boron modified with 2 wt. % vanadium pentoxide were investigated. The adsorption isotherms were analyzed in terms of their correspondence to the Brunauer – Deming – Deming – Teller (BDDT) classification and to the corresponding type of porosity, which is important for determining the potential application areas of the powders. It is shown that the type of chemical bonding in the adsorbent, its structure, and the features of surface formation during modification influence the adsorption and structural characteristics of the synthesized sample and allow its textural parameters to be controlled.
