• Characterization of the developed BN membranes.
• Testing membrane performance for water purification, including the removal of methyl orange, methylene blue, and Evans blue dyes.
• Comparative analysis with BN membranes produced via sonication-assisted liquid exfoliation in organic solvents.

Main Results:

• Water-exfoliated BN membranes achieved near 100% retention of water-soluble dyes (methyl orange, methylene blue, Evans blue).
• Membranes fabricated from water-exfoliated BN demonstrated superior performance compared to those produced using sonication in organic solvents.
• The developed membranes show high efficiency in water purification applications.

Conclusions:

• Water-exfoliated BN 2D nanosheets are highly effective for creating high-performance, environmentally friendly nanofiltration membranes.
