This method's benefits include its straightforward operation, simple workup, and use of an inexpensive, halogen-free MMPP oxidant that is easy to use and reasonably stable. All synthesized pyrazolyl sulfones were examined against bacterial and fungal strains, and notable antimicrobial activity was demonstrated by a few of the compounds. In order to investigate the prospect of connecting compounds with the highest yield and antimicrobial activity with their opto-electronic properties, time-resolved photoluminescence investigations for compounds 5a, 5b, and 5d were conducted. The tunable spectrum was observed in the micro-second time domain in all three cases, with fluorescent lifetime found higher in the compound having methyl group, intermediate with phenyl group, and lowest with the p-nitrophenyl group.

Fortunately, this challenge can be effectively addressed by employing a suitable substrate for the fabrication of MoS2/rGO heterostructures. Nanocomposites of MoS2/reduced graphene oxide (MoS2/rGO-700W and MoS2/rGO-560W) were synthesized using MoS2 and GO solutions as starting materials through microwave-assisted synthesis with microwave power treatments of 700W and 560W, respectively. Structural characterization results reveal that the particle size of MoS2 within the composites is notably smaller compared to that of pure MoS2. The MoS2/rGO-700W composite demonstrates a more homogeneous dispersion of MoS2 and features a well-developed hierarchical porous structure with increased pore volume and specific surface area. The MoS2/rGO-700W composite demonstrates elevated ID/IG ratio, C/O ratio and C = C peak area, suggesting that increased microwave power enhances the removal of oxygen-containing groups from rGO. This process significantly restores the extended conjugated structure of graphene, thereby offering enhanced conductivity at the MoS2 interface. Furthermore, the proposed strategy holds considerable theoretical value and provides significant insights for the development process of novel MoS2-based composite electrode materials.</div>","PeriodicalId":17081,"journal":{"name":"Journal of Sulfur Chemistry","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141882995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
