Halomethane Adsorption Studies on Silicane Sheets: A First-Principles Perception

Abstract

Silicane nanosheet (SiNS-hydrogenated version of silicene nanosheet) is employed as a base component in the current study to determine the presence of the halomethanes like fluoromethane, chloromethane, bromomethane, and iodomethane in the environment. The feasibility of the base component to sustain the physical modifications (upon the adsorption of the target vapors) is examined with the help of formation energy. In order to validate our suggestion of utilizing SiNS as a base component to detect halomethanes, electronic characteristics namely the band structure, electron density and projected density of states spectrum and surface assimilating features like the average energy gap variation, surface assimilation energy and Bader charge transfer are computed for pristine and halomethane adsorbed SiNS. The indispensable parameters estimated are compared, and the validity of our suggestion is confirmed in the current report. Graphic Abstract: [Figure not available: see fulltext.].
