Structure, Properties, and Applications of Graphite-Like Hexagonal Boron Nitride

Reduction of NOx on metal-free hydrogenated hexagonal boron nitride

“…Hexagonal boron nitride (hBN) consists of sp 2 hybridised boron and nitrogen atoms forming single-atom thick nanosheets. 31 These so-called '2D' nanosheets are held together by van der Waals forces and stacked in an ABAB pattern. 32 Due to the B-N bond's ionic character, charge localisation 33 hBN is an insulator with a large band gap of 6 eV.…”

Boron Nitride’s Morphological Role in the Design of Injectable Hyaluronic Acid Based Hybrid Artificial Synovial Fluid

“…Layered powders can adhere to the surface and form a protective boundary layer that minimizes the contact between the opposing surface roughness, which prevents abrasion. This boundary layer cannot resist the applied shear forces and acts as a lubricant on moving surfaces. − Hyaline cartilage can be defined as “biological bearing materials”. From an engineering point of view, the excellent solid lubricant properties of hBN particles as a new strategy to facilitate human joint movement have been suggested. , In the previous study, a new hybrid hydrogel strategy to facilitate movement in osteoarthritic joints was suggested, and novel hydrogel formulations containing hBN particles encapsulated in hyaluronic acid were described …”

Dehydrogenation of ammonia on free-standing and epitaxial hexagonal boron nitride

“…hBN consists of sp 2 hybridised N and B atoms forming 2D sheets. 16 Layers of hBN stack in an ABAB pattern held together by van der Waals forces. 17 Charge localisation gives hBN a large experimental band gap of 6 eV.…”

“…27 These promising results have sparked interest in hBN as a heterogeneous catalyst. Pristine hBN has several properties which are intrinsically suited for a catalyst, including high thermal stability, 16,36 a low coefficient of thermal expansion, 37 and high specific surface area. 38 The range of active sites available and the physical stability make hBN an excellent candidate for industrial catalysis.…”
