“…Hexagonal boron nitride ( h -BN) nanomaterials are a promising support for various metallic (Au, Ag, Pt, etc.) nanoparticles (NPs) used in heterogeneous catalysis [ 1 ]. These nanohybrids have shown their efficiency in the reactions of light alkene dehydrogenation [ 2 ], methane partial oxidation [ 3 ] and dry reforming [ 4 ], hydrogen peroxide generation [ 5 ], styrene production [ 6 ], and many others [ 7 , 8 , 9 , 10 , 11 , 12 , 13 ].…”

Micron-sized supports of catalytically active nanoparticles (NPs) can become a good alternative to nanocarriers if their structure is properly tuned. Here, we show that a combination of simple and easily scalable methods, such as defect engineering and polyol synthesis, makes it possible to obtain Ag and MgO nanoparticles supported on defective hexagonal BN (h-BN) support with high catalytic activity in the CO oxidation reaction. High-temperature annealing in air of Mg-containing (<0.2 at.%) h-BN micropellets led to surface oxidation, the formation of hexagonal-shaped surface defects, and defect-related MgO NPs. The enhanced catalytic activity of Ag/MgO/h-BN materials is attributed to the synergistic effect of h-BN surface defects, ultrafine Ag and MgO NPs anchored at the defect edges, and MgO/Ag heterostructures. In addition, theoretical simulations show a shift in the electron density from metallic Ag towards MgO and the associated decrease in the negative charge of oxygen adsorbed on the Ag surface, which positively affects the catalytic activity of the Ag/MgO/h-BN material.

“…BN nanoplates can retain their atomic structure up to 1150 K [ 7 ], undergoing oxidation at high temperatures with the formation of B 2 O 3 [ 8 ]. Therefore, h−BN sheets are potentially widely used in many applications, such as long-range ultraviolet light-emitting diodes, field emitters, and polymer matrix nanocomposites operating under extreme conditions [ 9 , 10 , 11 , 12 , 13 ].…”

In this work, we studied the oxidation stability of h−BN by investigating different variants of its modification by −OH, −O− and −O−O− groups using an atomistic thermodynamics approach. We showed that up to temperatures of ~1700 K, oxygen is deposited on the surface of hexagonal boron nitride without dissociation, in the form of peroxide. Only at higher temperatures, oxygen tends to be incorporated into the lattice of hexagonal boron nitride, except in the presence of defects Nv, when the embedding occurs at all temperatures. Finally, the electronic and magnetic properties of the oxidized h−BN were studied.

The use of nanoparticles (NPs) to modify the surface of cotton fabric is a promising approach to endowing the material with a set of desirable characteristics that can significantly expand the functionality, wear comfort, and service life of textile products. Herein, two approaches to modifying the surface of hexagonal boron nitride (h-BN) NPs with a hollow core and a smooth surface by treatment with maleic anhydride (MA) and diethylene triamine (DETA) were studied. The DETA and MA absorption on the surface of h-BN and the interaction of surfacemodified h-NPs with cellulose as the main component of cotton were modeled using density functional theory with the extended Perdew−Burke−Ernzerhof functional. Theoretical modeling showed that the use of DETA as a binder agent can increase the adhesion strength of BN NPs to textile fabric due to the simultaneous hydrogen bonds with cellulose and BN. Due to the difference in zeta potentials (−38.4 vs −25.8 eV), MA-modified h-BN NPs form a stable suspension, while DETA-modified BN NPs tend to agglomerate. Cotton fabric coated with surface-modified NPs exhibits an excellent wash resistance and high hydrophobicity with a water contact angle of 135°(BN−MA) and 146°(BN− DETA). Compared to the original textile material, treatment with MA-and DETA-modified h-BN NPs increases heat resistance by 10% (BN−MA fabric) and 15% (BN−DETA fabric). Cotton fabrics coated with DETA-and MA-modified BN NPs show enhanced antibacterial activity against Escherichia coli U20 and Staphylococcus aureus strains and completely prevent the formation of an E. coli biofilm. The obtained results are important for the further development of fabrics for sports and medical clothing as well as wound dressings.
