However, the traditional solvothermal method of synthesizing flexible COF film is usually complicated, long-term duration and energy-consuming, making it unsuitable for scalable preparation. To address these limitations, a new method combining electrospinning and sacrificial template is proposed to quickly produce triazine-based COF fiber films at room temperature. The method is easy to operate and has a short reaction time (minimum 0.5 h) without dehydration and deoxygenation processes at room temperature, making it suitable for large-scale production (20 cm × 30 cm). Different from the unprocessable of COF powder, COF films not only have good flexibility and mechanical properties, but also can be patterned with multiple functions to adapt to various application scenarios. Moreover, the functionality of triazine-structured COF is retained, enabling the use of the films in energy conversion and storage applications. Triazine-based COFs naturally have scalable conjugated structure, thus showing potential photocatalytic probability. Furthermore, the large pore structure of COF films enables loading of phase change materials endowing comprehensive properties of thermal management and flame retardance. This study proposes a strategy for the rapid synthesis of COF fiber films at room temperature and paves the way for multifunctional and high-performance COF based materials.</div></div>","PeriodicalId":15728,"journal":{"name":"Journal of Energy Chemistry","volume":"108 ","pages":"Pages 410-416"},"PeriodicalIF":13.1,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144071205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The construction of heterointerfaces is an effective strategy for enhancing both polysulfide adsorption and conversion; however, the poor lattice compatibility in the heterointerface formed by different materials hinders interfacial charge transfer. In response to these challenges, herein, a biphasic homojunction of TiO<sub>2</sub> enriched with oxygen vacancies and decorated with nitrogen-doped carbon nanotubes (B-TiO<sub>2−</sub><em><sub>x</sub></em>@NCNT) was designed to simultaneously enhance adsorption ability and catalytic activity. This homojunction interface composed of rutile (110) and anatase (101) plane exhibits excellent compatibility, and density functional theory (DFT) calculations reveal that this biphasic interface possesses a much higher binding energy to polysulfides compared to single-phase TiO<sub>2</sub>. Additionally, NCNTs are in situ grown on both interior and exterior surfaces of the hollow TiO<sub>2</sub> nanospheres, facilitating rapid electron transfer for the encapsulated sulfur. The homojunction interface synergistically leverages the oxygen vacancies and highly conductive NCNTs to enhance the bidirectional catalytic activity for polysulfide conversion. Therefore, in this multifunctional sulfur-host, polysulfides are first strongly adsorbed at the homojunction interfaces and subsequently undergo smooth conversion, nucleation, and decomposition, completing a rapid sulfur redox cycle.

Particularly, with multiple crosslinking and passivation sites, the incorporation of dipentaerythritol pentaacrylate (DPHA) can effectively improve the perovskite film quality, suppress nonradiative recombination, and block moisture erosion.
