Abstract
This study utilized DFT calculations to evaluate the interaction between SO2 gas and the surface of a B22 nanocluster decorated with Sc and Ti atoms as a chemical sensor. The optimized and electronic characteristics of pristine B22 and SO2 gas revealed that the pristine B22 was not a good candidate for sensing SO2 gas, and its electrical properties were not significantly altered. To improve the sensing properties of the B22 nanocluster, a decoration strategy was employed using Sc and Ti atoms. The results demonstrated that promising outcomes were achieved by decorating the B22 nanocluster with these metal atoms. After full optimization, two stable configurations were obtained between SO2 gas and the M/B22 structure; S7 (resulting from the interaction between Sc/B22 and SO2 gas) and S8 (resulting from the interaction between Ti/B22 and SO2 gas), with Eads values of −24.89 and −22.45 kcal/mol using the PBE/6-311G(d) level of theory, respectively. The electronic properties of the M/B22 structure were significantly altered after the adsorption of the SO2 molecule. The energy gap between HOMO and LUMO orbitals of S7 and S8 configurations was changed, which could be used as a chemical signal. Ultimately, we concluded that the M/B22 structure decorated with Sc and Ti atoms could be a potential sensor for the detection of SO2 gas.
期刊介绍:
The Journal of Sulfur Chemistry is an international journal for the dissemination of scientific results in the rapidly expanding realm of sulfur chemistry. The journal publishes high quality reviews, full papers and communications in the following areas: organic and inorganic chemistry, industrial chemistry, materials and polymer chemistry, biological chemistry and interdisciplinary studies directly related to sulfur science.
Papers outlining theoretical, physical, mechanistic or synthetic studies pertaining to sulfur chemistry are welcome. Hence the target audience is made up of academic and industrial chemists with peripheral or focused interests in sulfur chemistry. Manuscripts that truly define the aims of the journal include, but are not limited to, those that offer: a) innovative use of sulfur reagents; b) new synthetic approaches to sulfur-containing biomolecules, materials or organic and organometallic compounds; c) theoretical and physical studies that facilitate the understanding of sulfur structure, bonding or reactivity; d) catalytic, selective, synthetically useful or noteworthy transformations of sulfur containing molecules; e) industrial applications of sulfur chemistry; f) unique sulfur atom or molecule involvement in interfacial phenomena; g) descriptions of solid phase or combinatorial methods involving sulfur containing substrates. Submissions pertaining to related atoms such as selenium and tellurium are also welcome. Articles offering routine heterocycle formation through established reactions of sulfur containing substrates are outside the scope of the journal.
