摘要

The adsorption and dissociative reaction of methanol on B12N12 fullerene-like nanocage is investigated by using density functional calculations. Equilibrium geometries, adsorption energies, and electronic properties of CH3OH adsorption on the surface of the B12N12 were identified. The calculated adsorption energies range from -1.3 to -34.9 kcal/mol. It is found that the electrical conductivity of the nanocage can be modified upon the adsorption of CH3OH. The mechanism of methanol decomposition via C-O and O-H bond scissions is also studied. The results indicate that O-H bond scission is the most favorable pathway on the B12N12 surface.

A comparative study of Mannosylerythritol lipids (MELs) surfactant adsorption upon the Al12N12 and B12N12 nano-cages as potential candidates for detecting MELs

Hossein Khalafi, Sara Ahmadi

Summary: This paper investigates the adsorption of MELs on aluminum nitride and boron nitride nanocages in the solution phase. The results show that ether oxygen atoms exhibit stronger adsorption on aluminum nanocages, while the hydroxyl group oxygen has stronger adsorption on boron nitride nanocage. Thermodynamic calculations demonstrate that all adsorption positions of aluminum nitride are favorable, but some positions of boron nitride are unfavorable. In terms of recovery time, boron nitride is not an ideal adsorbent due to its very short recovery time. Aluminum nitride may serve as a suitable sensor for MELs in the solution phase, while boron nitride does not significantly alter the number of conducting electrons.

Density Functional Theory Study of Cu-Modified B12N12 Nanocage as a Chemical Sensor for Carbon Monoxide Gas

Adilson Luis Pereira Silva, Jaldyr de Jesus Gomes Varela Junior

Summary: This study focused on the development of B12N12-based toxic gas sensors using quantum chemical calculations. The results showed that the introduction of copper improved the gas adsorption performance of B12N12, but the interaction between CO and certain modified structures limited their application as sensors. Among the studied systems, CuB11N12 exhibited moderate adsorption and high electronic sensitivity, with a short recovery time and high selectivity, making it a promising fast response sensor material for the selective detection of CO gas.

Adilson Luis Pereira Silva, Jaldyr de Jesus Gomes Varela Junior

Summary: The development of sensors for hazardous gases based on metal-modified B12N12 nanocages has attracted attention. In this study, the interactions between CNCl toxic gas and pristine and MB11N12 (M = Fe, Co, Ni, Cu, and Zn) nanocages were evaluated using density functional theory (DFT). The results showed that doping reduced the energy band gap (E-gap), with the strongest interaction observed on FeB11N12 and CoB11N12 nanocages. NiB11N12 and CuB11N12 nanocages exhibited the highest electronic sensitivity for CNCl gas adsorption, making them superior sensor materials for detecting CNCl toxic gas.

Computational study on nickel doped encapsulated Mg, K, Ca on pristine C24 nanocage for gas sensing applications

Adanna D. Nwagu, Hitler Louis, Henry O. Edet, Innocent Benjamin, Vincent N. Osabor, Adedapo S. Adeyinka

Summary: Intense attention has been given to environmental sustainability due to high greenhouse gas emissions. This study focuses on the adsorption and sensing properties of nickel-doped encapsulated Mg, K, Ca on pristine C24 nanocage for CO2, NO2, and SO2 gases using density functional theory (DFT) method. Two adsorption models were designed based on the shape of the gas molecules, and various factors including adsorption energy, electronic properties, weak interactions, dipole moment, and reusability were considered. The results provide comprehensive reference for the selectivity of the adsorbents' modification towards the effective sensing of these toxic gases. The encapsulation of K, Ca, Mg, and late transition metal dopant enhances the adsorbents, leading to improved surface properties.
