Abstract:

Abstract: The opteoelectronical properties of B12N12 nano-cage was investigated in thepresent of some metals by density functional theory (DFT). After the adsorption of atoxic molecule with all complexes, the electronic properties in B11GeN12 nano-cagewere significantly increased. The UV-Vis adsorption and Infrared spectroscopy ofcyanogen chloride over the B11GeN12 have been performed by the time-dependentdensity functional theory (TD-DFT). The increasing of λmax values from the pristineB12N12 to B11GeN12, reveals that B11GeN12 nano-cages can be a suitable structure asoptic sensor for this gas detection. Overall, Because of the crystalline defect, Symmetrydisruption and the changes in the degree of polarization, the semiconductor propertyaffects these nano-cage systems. Finally, the changes of energy of gap (Eg) with asignificant charge transfer from this gas to Ge-doped nano-cage, which lead to changesof conductance of it and render this kind of system sufficient for gas detection.

HNO Detection by Nanosized B12N12 Cage: A DFT/TDDFT Study

The interaction of a nitrosyl hydride (HNO) molecule with B12N12 nanocage was explored by means of density functional calculations. It was found that HNO prefers to be adsorbing on a boron atom of the cage with adsorption energy of -0.65 eV. This adsorption process significantly shifts the HOMO-LUMO gap (Eg) of the cage to lower energies, thereby reducing Eg of the cage from 6.84 to 2.45 eV. Ti...

The NBO, AIM, MEP, thermodynamic and quantum parameters investigations of Pyrrole 2-carboxylic acid molecule adsorption on the pristine and Ni doped B12N12 nano cage

ABSTRACT The main objective of this work is to investigate the adsorption of Pyrrole 2-carboxylic acid (PCA) from O, N and C sites on the surface of pristine and Ni doped B12N12 nano cage by using density functional theory (DFT). The results of adsorption energy indicate that the adsorption of PCA on the surface of B12N12 and NiB11N12 is exoth...

Sensing Performance of Sc-doped B12N12 Nanocage for Detecting Toxic Cyanogen Gas: A Computational Study

Adsorption of cyanogen molecule on the surface of pristine and Sc-doped B12N12 nanocage is scrutinized using at DFT calculations to investigating its potential as chemical nanosensors. The results show that cyanogen is weakly adsorbed on the pristine B12N12 and consequently its electrical properties are changed insignificantly. In order to improve the...

Adsorption of proline amino acid on the surface of fullerene (C20) and boron nitride cage (B12N12): A comprehensive DFT study

In this study, the performance of fullerene (C20) and boron nitride cage (B12N12) as a sensing material for detection of proline was evaluated by density functional theory. For this purpose, the structures of proline, C20, B12N12 and the derived products from the proline adsorption on the surface of nanostructures were optimized geometrically. Then, IR and Frontier molecular orbital calculation...

Be12O12 Nano-cage as a Promising Catalyst for CO2 Hydrogenation

An efficient conversion of CO2 into valuable fuels and chemicals has been hotly pursued recently. Here, for the first time, we have explored a series of M12x12 nano-cages (M = B, Al, Be, Mg; X = N, P, O) for catalysis of CO2 to HCOOH. Two steps are identified in the hydrogenation process, namely, H2 activation to 2H*, and then 2H* transfer to CO2 forming HCOOH, where the barriers of two H* tran...
