However, the extraction and purification of SAB from natural products are hindered by the complexity and low concentration of matrix components. In this research, a new surface imprinted polymer with core-shell structure, denoted as ZIF-8@MIPs, was successfully developed using porous metal-organic frameworks (MOF) ZIF-8 as the scaffold. ZIF-8@MIPs exhibited remarkable selective extraction and enrichment of SAB from Salviorrhiza. Series of characterizations and adsorption experiments demonstrated that ZIF-8@MIPs possessed a typical core-shell octahedral structure with a high specific surface area. The resultant high-density imprinted sites allowed the ZIF-8@MIPs to exhibit a high adsorption capacity (46.7 mg/g) and exceptional selectivity (IF = 3.11) for SAB, while achieving adsorption equilibrium within 90 min. Notably, the ZIF-8@MIPs maintained an adsorption capacity of 89.2% for SAB after 7 cycles of adsorption-desorption experiments, indicating good reusability. Furthermore, a solid-phase extraction column was established utilizing the ZIF-8@MIPs as the adsorbent, and the content of SAB in the Salviorrhiza extract was determined by combining this with HPLC. The spiked recovery rate ranged from 87.70 to 92.90%, with RSD of 2.87–3.43%, demonstrating the reliability and reproducibility of this method. In conclusion, the ZIF-8@MIPs developed in this study offer a promising approach for the selective extraction of active flavonoids from natural matrices, with potential application in application prospects.","PeriodicalId":761,"journal":{"name":"Russian Journal of General Chemistry","volume":"95 9","pages":"2457 - 2467"},"PeriodicalIF":0.8,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145236731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, cobalt-based catalysts have garnered significant attention in PDH research due to their advantages such as relatively low cost, abundant active components, and tunability. This paper reviews the research progress of cobalt-based catalysts in PDH. Active cobalt can exist in various forms within the catalyst, including single-atomic Co that can precisely regulate propane adsorption and activation, prevalent tetrahedral Co(II) sites that interact significantly with the support material, and even metallic Co particles. However, the industrial application of cobalt-based catalysts still faces substantial challenges, including high-temperature deactivation of active sites, unclear carbon deposition kinetics, and excessive costs associated with large-scale synthesis. To address these issues, this paper systematically discusses strategies for enhancing catalyst performance, including adjustment of the active site microenvironment (additive doping and support modification), optimization of the catalyst interface (acid-base balance adjustment and pore structure design), and improvement of catalyst stability (multi-component synergistic strengthening). In addition, considering the challenges faced in the PDH reaction using Co-based catalysts, we summarize the corresponding regulatory strategies, providing novel insights and valuable guidance for the development of efficient PDH catalysts.","PeriodicalId":761,"journal":{"name":"Russian Journal of General Chemistry","volume":"95 9","pages":"2309 - 2320"},"PeriodicalIF":0.8,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145236931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
