Among them, small-pore SSZ-13 stands out as an artificial aluminosilicate zeolite with CHA topology. Since its invention in 1985, SSZ-13 zeolite has garnered significant attention in both academia and industry due to its exceptional performance in heterogeneous catalysis, gas adsorption and separation. Modification of its physicochemical properties to meet the diverse requirements of various application scenarios has become a prominent topic in zeolite research. Considerable efforts have been devoted to alleviating the diffusion limitations inherent in micropores by downsizing crystal size or introducing additional mesopores and/or macropores to construct hierarchical structures. Regulating framework Al atoms in isolation or pairing introduces remarkable catalytic or adsorptive diversity into compositionally similar SSZ-13 zeolites. The conventional synthesis of SSZ-13 zeolite, which involves the use of expensive and toxic <em>N</em>,<em>N</em>,<em>N</em>-trimethyl-1-adamantylammonium hydroxide (TMAdaOH) as an organic structure-directing agent (OSDA) and a hydrothermal crystallization process lasting typically more than four days, severely hinders its cost-effective utilization. In response, extensive research endeavors have been dedicated to developing innovative synthetic approaches for SSZ-13 zeolites aimed at greener, more efficient, and economically viable production. This article presents a comprehensive overview of recent research developments in the field of SSZ-13 zeolites, encompassing novel synthetic methods, hierarchical engineering, nanocrystal technology, Al distribution, fast synthesis, and cost reduction techniques, aiming to provide valuable insights and guidance to relevant researchers.</p></div>","PeriodicalId":100892,"journal":{"name":"Materials Today Catalysis","volume":"4 ","pages":"Article 100037"},"PeriodicalIF":0.0,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949754X23000376/pdfft?md5=286cac8cb85d22296b84455e19b82f69&pid=1-s2.0-S2949754X23000376-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138616215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review, we summarize a series of progress and achievements made by first-principle-based theoretical models in analyzing the shape evolution of metal NPs and surface segregation of alloys under different gas conditions in recent years.

However, the fabrication of a well-suited Z-scheme remains a challenge. In this work, we constructed a Z-scheme system with a suitable band structure by in-situ hydrothermal growth of In₂S₃ nanosheets on electrospun Fe₃C/Carbon fibers with 3D structure. The Z-scheme electron transport path is verified by the calculation of the energy band structure calculation and the method of photodeposition, indicating that In₂S₃ and Fe₃C are reduction reaction sites and oxidation reaction sites respectively. Carbon fibers serve as both the skeleton of the 3D structure and the electron mediator from Fe₃C to In₂S₃. Moreover, the DFT calculation demonstrates that the introduction of Fe₃C can reduce the energy barrier of *CO and *COH coupling on In₂S₃, and weaken the bonding of In-S, thereby enhancing the product selectivity towards acetate. Owing to the efficient charge transfer of the Z-scheme system, the photocorrosion in In₂S₃ is also greatly reduced, showing a relatively stable chemical composition after several hours of reaction. Compared with In₂S₃ and Fe₃C/C, In₂S₃-C/Fe₃C composites showed a significantly increased acetate evolution rate of 11.33 μmol/h/g without any sacrificial reagents.
