Abstract
Fabricating efficient sensors for detecting various gasses is one of the major challenges in environmental monitoring and safety. There has been extensive research in recent years into the applications of 2D nanomaterials as gas sensors thanks to their great surface-to-volume ratio as well as adjustable electronic characteristics. The current study, by employing DFT, aimed at examining the sensing capability of graphene-based ternary (Boron)x-(Nitrogen)y-(Carbon)z for (x = y = 1, z = 2) (BNC2) in detecting gasses, with a particular emphasis on the adhesion of H2, H2S, NO2, and SO2 onto both bare and platinum-doped BNC2 (Pt@BNC2). The findings indicated that the Pt atom exhibited a strong binding affinity to the BNC2, albeit with a slight protrusion from the plane. The Pt@ BNC2 demonstrated the most robust interaction with gasses, especially NO2 and SO2. The charge transport analysis revealed that the majority of gasses functioned as acceptors of charges, with NO2 and SO2 displaying considerable electron acquisition from the Pt@BNC2. Furthermore, recovery time analyses indicated that doping the Pt atom significantly improved the capability of Pt@BNC2 in sensing gasses in comparison to the bare BNC2, particularly in detecting NO2 and SO2. The current study highlighted the adaptability of Pt@BNC2 in both sensing and capturing gasses, being conducive to fabricating sophisticated sensing devices and preserving the environment.
期刊介绍:
The Journal of Molecular Graphics and Modelling is devoted to the publication of papers on the uses of computers in theoretical investigations of molecular structure, function, interaction, and design. The scope of the journal includes all aspects of molecular modeling and computational chemistry, including, for instance, the study of molecular shape and properties, molecular simulations, protein and polymer engineering, drug design, materials design, structure-activity and structure-property relationships, database mining, and compound library design.
As a primary research journal, JMGM seeks to bring new knowledge to the attention of our readers. As such, submissions to the journal need to not only report results, but must draw conclusions and explore implications of the work presented. Authors are strongly encouraged to bear this in mind when preparing manuscripts. Routine applications of standard modelling approaches, providing only very limited new scientific insight, will not meet our criteria for publication. Reproducibility of reported calculations is an important issue. Wherever possible, we urge authors to enhance their papers with Supplementary Data, for example, in QSAR studies machine-readable versions of molecular datasets or in the development of new force-field parameters versions of the topology and force field parameter files. Routine applications of existing methods that do not lead to genuinely new insight will not be considered.
