To address this issue, in the article numbered e270043, Yang et al. successfully synthesized ultrafine truncated octahedral titanium dioxide nanocrystals (P-O_v-TiO₂) with specific {101} crystal faces, phosphorus doping, and oxygen vacancies under mild conditions. The oxygen vacancies significantly enhance the electron enrichment and charge transfer ability by adjusting the electronic structure; phosphorus doping effectively optimize the <i>d</i>-band center of the catalyst, further strengthening the titanium-sulfur interaction at the {101} crystal faces. This dual-defect engineering enables the exposed {101} crystal faces to exhibit excellent chemical adsorption capacity and catalytic performance. The assembled lithium-sulfur battery using P-O_v-TiO₂ as the separator modification achieves a high specific capacity of 895 mAh g^-1 at 5 C and exhibites a minimal decay rate of 0.14% per cycle over 200 cycles. Additionally, the lithium-sulfur pouch battery delivers a high capacity of 1004 mAh g^-1 under a 0.1 C current density in a low electrolyte condition. This research provides important theoretical basis and new ideas for designing efficient catalysts suitable for lithium-sulfur battery applications.\u0000\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":33706,"journal":{"name":"Carbon Energy","volume":"7 8","pages":""},"PeriodicalIF":24.2,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cey2.70085","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144909927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most developed catalytic materials still suffer from insufficient mass diffusion and unsatisfactory durability due to the lack of interconnected and regulatable porosity. Developing catalytic architectures with engineered active sites and prominent stability through rational synthesis strategies has become one of the core projects in solar-driven applications. The unique properties of mesoporous silicas render them among the most valuable functional materials for industrial applications, such as high specific surface area, regulatable porosity, adjustable surface properties, tunable particle sizes, and great thermal and mechanical stability. Mesoporous silicas serve as structural templates or catalytic supports to enhance light harvesting via the scattering effect and provide large surface areas for active site generation. These advantages have been widely utilized in solar applications, including hydrogen production, CO₂ conversion, photovoltaics, biomass utilization, and pollutant degradation. To achieve the specific functionalities and desired activity, various types of mesoporous silicas from different synthesis methods have been customized and synthesized. Moreover, morphology regulation and component modification strategies have also been performed to endow mesoporous silica-based materials with unprecedented efficiency for solar energy storage and utilization. Nevertheless, reviews about synthesis, morphology regulation, and component modification strategies for mesoporous silica-based catalyst design in solar-driven applications are still limited. Herein, the latest progress concerning mesoporous silica-based catalysis in solar-driven applications is comprehensively reviewed. Synthesis principles, formation mechanisms, and rational functionalities of mesoporous silica are systematically summarized. Some typical catalysts with impressive activities in different solar-driven applications are highlighted. Furthermore, challenges and future potential opportunities in this study field are also discussed and proposed.

Herein, we present a viable strategy to recycle Pb and iron (Fe) from Pb–Zn slags for the fabrication of efficient methylammonium lead tri-iodide (r-MAPbI₃) piezocatalysts with single-atom Fe–N₄ sites. Intriguingly, atomically dispersed Fe sites from Pb–Zn slags, which coordinated with N in the neighboring four CH₃NH₃ to form the FeN₄ configuration, were detected in the as-obtained r-MAPbI₃ by synchrotron X-ray absorption spectroscopy. The introduction of Fe single atoms amplified the polarization of MAPbI₃ and upshifted the d-band center of MAPbI₃. This not only enhanced the piezoelectric response of MAPbI₃ but also promoted the proton transfer during the hydrogen evolution process. Due to the decoration of Fe single atoms, r-MAPbI₃ showed a pronounced H₂ yield of 322.4 μmol g⁻¹ h⁻¹, which was 2.52 times that of MAPbI₃ synthesized using commercially available reagents.
