Strategically, to increase the transport channel of macromolecules and shorten the transport path, it is necessary to introduce mesoporous structures into zeolite. Here, we report a solid-state synthesis of hierarchical TS-1 zeolite by optimizing carbon black sequence. The texture property of hierarchical TS-1 can be optimized by carbon black. Most importantly, the addition sequence of carbon black can impact the porosity of hierarchical TS-1. The hierarchical zeolite is synthesized by incorporating 0.2 g carbon black into the seeds. When carbon black is firstly combined with seeds, the enhanced interaction facilitates the subsequent growth process, leading to large surface area from mesopores (121 m<sup>2</sup>/g) and abundant pores size (8–40 nm) and enhanced exposure of Ti active sites. The optimized hierarchical TS-1 possesses excellent catalytic performance with high conversion rate (24.4 %) and similar selectivity (93.8 %), which are 1.6 times higher than that of traditional TS-1 zeolites.</div></div>","PeriodicalId":378,"journal":{"name":"Journal of Solid State Chemistry","volume":"347 ","pages":"Article 125339"},"PeriodicalIF":3.2,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706348","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}
