Abstract
Porous boron nitride (BN) is structurally analogous to activated carbon. This material
is gaining increasing attention for its potential in a range of adsorption and chemical
separation applications, with a number of recent proof-of-concept studies on the removal
of organics from water. Today though, the properties of porous BN—i.e., surface area,
pore network, chemistry—that dictate adsorption of specific organics remain vastly
unknown. Yet, they will need to be optimized to realize the full potential of the material
in the envisioned applications. Here, a selection of porous BN materials with varied pore
structures and chemistries were studied for the adsorption of different organic molecules,
either directly, through vapor sorption analyses or as part of a water/organic mixture in the
liquid phase. These separations are relevant to the industrial and environmental sectors
and are envisioned to take advantage of the hydrophobic character of the BN sheets.
The materials were tested and regenerated and their physical and chemical features
were characterized before and after testing. This study allowed identifying the adsorption
mechanisms, assessing the performance of porous BN compared to benchmarks in the
field and outlining ways to improve the adsorption performance further.
