“…The hBN nanostructure and hBN-dye conjugates were dispersed in ultra-pure water and the surface charges were determined using zeta potential measurements before and after adsorption. The measurements of the zeta potential are shown in Table 1 and were confirmed with the described values for kinds of BN materials in the literature due to the B-OH and N-OH generated on the hBN in water [41][42][43]. According to Table 1, the zeta potential of the hBN decreased after the adsorption of VBB, whereas it increased after the adsorption of MY.…”

The purpose of this study was to compare the adsorption behavior of cationic and anionic dyes onto a hexagonal boron nitride (hBN) nanostructure that was rich in a negative charge. Herein, the hBN nanostructure was synthesized using boric acid as a precursor material. The characteristic peaks of the hBN nanostructure were performed using Fourier transform infrared (FT-IR) and Raman spectroscopies. The morphology and the particle size of hBN nanostructure were determined by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). During the studies, various essential adsorption parameters were investigated, such as the initial dye concentration, pH of the dye solution, adsorbent dose, and contact time. Under optimal conditions, the removal of 42.6% Metanil yellow (MY) and 90% Victoria blue B (VBB) from aqueous solution was performed using a 10-mg hBN nanostructure. Furthermore, the equilibrium studies showed that the Freundlich isotherm model fitted well for the removal of MY. However, the Langmuir isotherm model fitted well for the removal of VBB. Moreover, according to the results obtained from the kinetic studies, while the first-order kinetic model was suited for the adsorption of the MY, the second-order kinetic model was found to well fit for the adsorption of VBB.

“…Considering the negative ζ-potential in this range a hydrogen terminated diamond seed solution, which shows positive ζ-potential 31 , is ideal for seeding the ceramic for diamond growth. Similar negative potential has also been seen for BN solutions 32,33 . In the literature, higher negative ζ-potential in boron ceramics has been attributed to low content of B 2 O 3 32,34 .…”

Superconducting boron doped nanocrystalline diamond on boron nitride ceramics

In this work we have demonstrated the growth of nanocrystalline diamond on boron nitride ceramic. We measured the zeta potential of the ceramics to select the diamond seeds. Diamond was then grown on the seeded ceramics using a microwave chemical vapour deposition system. A clear difference was found between the samples which were seeded with nanodiamond and the ones not seeded before growth. Raman spectroscopy confirmed the excellent quality of the diamond film. Dielectric measurements showed an increase in the dielectric constant of the material after diamond growth. The diamond was also doped with boron to make it superconducting. The film had a transition temperature close to 3.4K. Similar strategies can be applied for growth of diamond on other types of ceramics.

“…The white translucent and stable colloidal solution containing few-layer BN (Figure 1a) shows a highly negative zeta potential at −33.9 ± 0.9 mV (pH ∼ 7), in agreement with a previous work, 4 due to the B−O−H and N−O−H groups generated at the interface between h-BN and water. 4,40 The atomic force microscopy (AFM) image and the height profile in Figure 1b show that most of the BN sheets are about 1.5 nm in thickness, corresponding to around 5 atomic layers, and have a narrow lateral size in the range of 50−100 nm.…”

High and Stable Ionic Conductivity in 2D Nanofluidic Ion Channels between Boron Nitride Layers

et al. 2017

Achieving a high rate of ionic transport through porous membranes and ionic channels is important in numerous applications ranging from energy storage to water desalination, but it still remains a challenge. Herein we show that ions can quickly pass through interlayer spaces in hydrated boron nitride (BN) membranes. Measurements of surface-charge governed ionic currents between BN nanosheets in a variety of salt solutions (KCl, NaCl and CaCl) at low salt concentrations (<10 M) showed several orders of magnitude higher ionic conductivity compared to that of the bulk solution. Moreover, due to the outstanding chemical and thermal stability of BN, the ionic conduits remain fully functional at temperatures up to 90 °C. The BN conduits can operate in acidic and basic environments and do not degrade after immersing in solutions with extreme pH (pH ∼ 0 or 14) for 1 week. Those excellent properties make the BN ionic conduits attractive for applications in nanofluidic devices and membrane separation.
