| contents | Why is the question in the title pertinent? Toxic gases, which are detrimental to both human health and the environment, have been released in greater quantities as a result of industrial development. These gases necessitate capture, immobilization, and measurement. Consequently, the present study investigates the interactions between boron-nitride nanobelt and Möbius-type boron-nitride nanobelt and nine greenhouse gases, namely ammonia, carbon dioxide, carbon monoxide, hydrogen sulfide, methane, methanol, nitric dioxide, nitric oxide, and phosgene. The adsorption energies calculated for the structures with optimized geometry are all negative, suggesting that all gases are adsorbed favorably in both nanobelts. Furthermore, we discovered that the recovery time of the sensors ranges from two hours to a few nanoseconds, and that the nanobelts exhibit distinct responses to each gas. According to electronic and topological investigations, covalent bonds were exclusively formed by nitric oxide; the remaining gases formed non-covalent bonds. Molecular dynamics ultimately demonstrate that the interaction between a single gas molecule and the nanobelt remains consistent across the vast majority of gases, whereas the interaction between 500 gas molecules and the nanobelts functions as an attraction, notwithstanding the impact of volumetric effects characteristic of high volume gases on the interaction. For the completion of each calculation, semiempirical tight-binding methods were implemented utilizing the xTB software. The outcomes of our study generated a favorable response to the inquiry posed in the title. |
