The nature and interlayer interactions of the as-synthesized BN materials were also characterized by Raman spectroscopy (Figure 4b). The Raman spectra of the T-BN and F-BN show specific peaks at ∼1371 and ∼1369 cm−1, respectively, corresponding to the B–N vibration mode (E2g). The full width at half maximum (FWHM) was determined to be ∼35 and ∼24 cm−1 for T-BN and F-BN, respectively. The larger FWHM value and higher wavelength demonstrated a low crystalline structure along with the low interlayer interactions at T-BN as compared to that of F-BN [32–34]. The intermolecular bonding and chemical properties of the as-synthesized BN were characterized by FTIR spectroscopy (Figure 4c). The FTIR analysis of T-BN shows two strong absorption peaks at ∼1382 and ∼790 cm−1, ascribed to the in-plane B–N transverse stretching vibration and the B–N–B out-of-plane bending vibration, respectively [35–37]. The broad absorption peaks at ∼3415 and ∼3227 cm−1 indicate the presence of residual B−OH and B−NH2 groups, respectively. The same FTIR results are also observed for F-BN. However, the higher intensity of the IR peaks of F-BN as compared to that of T-BN indicates the existence of stronger interlayer interaction because of the presence of more number of amino functional groups at the F-BN surface, strongly reducing the porosity and decreasing the surface area of the F-BN materials [38]. Then, the SSA and pore size distribution of the as-synthesized BN products were determined by nitrogen
