Supported cobalt-based catalysts exhibit significant activity in FTS, but their product selectivity requires further optimization. In this paper, Co@SiO2 catalysts with core-shell structure were prepared by hydrothermal synthesis. The effect of the SiO2 shell thickness on the catalytic performance of FTS was explored by varying the amount of ethyl orthosilicate (TEOS) added with stabilizer polyvinylpyrrolidone (PVP). Among them, the catalyst CS3 achieved the greatest number of cobalt active sites, the highest CO conversion (77.2%), and C5+ selectivity (84.3%) with a high C5-C11 proportion in the C5+ product. Characterizations of the catalysts were performed to examine their morphology and physicochemical properties. It was observed that the dispersion of cobalt species improved with increasing shell thickness within a certain range, promoting the reduction of cobalt species. However, the formation of Si-OH groups because of the hydrolysis of excess TEOS clogged catalyst pores, consequently diminishing the catalytic activity in FTS. Compared with the CS3-PVP0 catalyst without stabilizer PVP added, the catalyst CS3 with PVP added exhibited obvious ordered morphology, making CO conversion significantly enhanced. This is attributed to the role of inert carbon in PVP, which not only boosts the reducibility of cobalt species but also enhances the surface hydrophobicity of the mesoporous SiO2 material.\u0000 </div>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"39 3","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143404450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it was only in 1820 that quinine had its structure elucidated, and subsequently, during the 20th century, several synthetic derivatives were produced with quinine superior activities. In parallel, the search for the synthesis of metal complex compounds for the treatment of malaria dates from 1994, with the development of ferroquine, an iron complex derived from chloroquine, developed by Biot and collaborators at Lille University. After, there are several metal complexes synthesized from quinine with various metals, such as ruthenium, gold, iridium, and platinum, over the last 30 years, which are the aims of this review. This review identified 84 quinoline–metal complexes reported across 25 studies, with the gold complex (Complex 63) showing significant potency against the FcBI strain (IC50 10 nM), outperforming chloroquine (CQ, 50 nM), indicating that metal coordination enhances the drug's action. The ruthenium complex (Complex 03) exhibited activity against PFB but was less effective than CQ (IC50 22.5 vs. 8.2 nM). Other complexes, such as Au(III) (Complex 61), Ir(I) (Complex 52), and Ir(II) (Complex 50), also demonstrated promising results with varying effectiveness across different strains. Structural features, including linear geometry in Au(I) complexes and square planar or piano stool geometries in Ru(II) and Ir complexes, play crucial roles in influencing their biological activity. These findings highlight the potential of metal coordination in improving antimalarial efficacy.\u0000 </div>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"39 3","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that copper nanoclusters are successfully loaded on MOF-199, and the morphology and crystal structure of the modified MOF-199 do not change significantly compared with pure MOF-199. However, the type of solvent and the content of copper nanoclusters affect the specific surface area and pore size of MOF-199.
