Adsorption of nitrogen oxides on modified BN nanosheets: improved gas sensing and functionalization

Abstract

The sensing mechanism of modified hexagonal boron nitride to nitrogen oxide molecules (NO, NO2 and N2O) was systematically investigated by using the density functional theory calculations. The results indicate that...

A theoretical study on the mechanism of conversion of C3H8 and CO2 to C3H6 and HCOOH by M4–B24N28 catalysis

“…When a B atom disappears, the force balance between the B and N atoms is broken, and then different metals are introduced for doping, so that different degrees of orbital hybridization occur between the metal atom and the N atom, which promotes the change of the surface activity of the catalyst. 34 The Cu 4 –B 24 N 28 surface catalyzed the initial oxidation of propane with the lowest activation energy of 1.58 eV, and the preliminary oxidation of propane is more inclined to the dehydrogenation of secondary carbon, that is, the C–H bond of the methylene group is preferentially broken, which is consistent with the conclusions obtained from related experiments. 55–57…”

“…Such metal-free BN-based catalysts are similar to non-metallic carbon-based catalysts, their catalytic properties can be easily tuned, and they exhibit good low-temperature ODHP performance. 33,34 In the field of heterogeneous catalysis, BN-based materials are usually used as supports. In addition, they can also be used as promoters to enhance the catalytic reaction by adjusting the interaction between the catalyst surface and the metal.…”

Boron Nitride Nanosheet–Magnetic Nanoparticle Composites for Water Remediation Applications

“… 5 BNNSs have unique properties such as high surface area and high thermal stability; they are chemically inert and stable to oxidation. These unique properties make the BNNS an attractive material for applications such as pollutant removal, 3 lubricants, 6 sensing applications, 7 and super hydrophobic coatings. 8 Magnetic nanoparticles are another material with unique properties, namely, their magnetic functionality and large surface area.…”
