Two-dimensional hexagonal boron nitride is a fascinating nanomaterial with a broad range of potential applications. However, further development of this nanomaterial is hampered because of its poor functionality and low processability. One of the efficient strategies for improving the processability of two-dimensional hexagonal boron nitride is the covalent functionalization of this nanomaterial. In this study, we report on a straightforward approach for functionalization of two-dimensional hexagonal boron nitride by lithium cyclopentadienyl and its application for water treatment. Cyclopentadienyl-functionalized boron nitride was characterized by different spectroscopy and microscopy methods as well as thermal and BET analysis. The synthesized nanomaterial was able to efficiently remove methylene blue from water in a short time. Adsorption capacity of this nanomaterial was as high as 476.3[Formula: see text]mg/g, which was superior to the nonfunctionalized boron nitride. Our results showed that cyclopentadienyl-functionalized boron nitride is a promising candidate for the removal of cationic pollutants from water.

In recent years have seen a surge of increased interest in the exfoliation of boron nitride (h-BN) due to its exciting electrical, thermal, photonics mechanical properties and sensing. Several approach to have emerged describing the exfoliation, functionalized and solubilization of h-BN. In this study, we report on a straightforward approach to modify the surface and its application as a new type of biomedical applications. The prepared product is structurally characterized by FTIR spectroscopy, field emission (FESEM), TGA technique, XPS spectrum, and BET surface area measurements. Nano- composites were immobilized on electrodes to detect the glucose, L-cysteine in buffer medium by cyclic voltammetry (CV), square wave voltammetry (SWV), and impedance spectroscopic (EIS). potential application of the covalent functionalization, cheap precursors, biodegradability and multifunctionality of high-performance composites boron nitride, they could be used for a wide range of the future biomedical applications.
