Three distinct doping patterns involve two identical or different transition metals across 27 candidates. Machine learning (ML) based models were developed with high accuracy to predict the catalytic activity of unknown catalysts. The scaling relation between the adsorption energies of *CO and *CHO is circumvented by regulating the local environment with preferential dual atom doping. The integrated DFT+ML approach identifies 14 and 8 most suitable DAAs for C1 and C2 product formation, respectively.

This study explores metallic nickel boride (NiB) as a catalyst to enhance charge transfer and LiPS conversion. Theoretical and experimental results reveal that NiB accelerates sulfur redox kinetics, significantly improving the battery performance. With a sulfur loading of 5 mg cm–2 cycled at 0.5 C, the NiB-based battery achieved a discharge capacity of 1239 mAh g–1, retaining 83.2% after 150 cycles. Even at a current density of 14.89 mA cm–2, it maintained a capacity of 590 mAh g–1 with a low decay rate of 0.07%.

This new approach not only simplifies the synthesis process but also significantly expands the types of chemical linkages available for COF construction. The resulting En-COF-P exhibits an enhanced visible light absorption range, facilitating improved charge generation and separation. These properties translate into remarkable photocatalytic performance, particularly in the blue-light-driven selective oxidation of organic sulfides, where En-COF-P achieves up to 99% conversion and 99% selectivity. Remarkably, En-COF-P’s photocatalytic efficiency is eight times higher than that of traditional imine-linked COFs. This work underscores the potential of click polymerization in COF synthesis and advances a new strategy for the design of highly efficient photocatalysts.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"6 12","pages":"5292–5299 5292–5299"},"PeriodicalIF":9.6,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142756495","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}

Magnetron sputtering is a commercially available and highly reliable technique that is highly attractive for applications in the production of perovskite films. Here, the ion deposition of the step-by-step sputtering process and the continuous sputtering process was systematically explored to realize the controlled ion deposition and crystallization of sputtered perovskite films. We found that the deposition rate of organic components in the initial sputtering stage is greater than that of inorganic components, leading to the ion ratio of perovskite thin films being accurately regulated by adjusting the sputtering time. Furthermore, the injected content of methylammonium bromide will significantly affect the ion ratios and crystal structures of the sputtered perovskite films. The efficiency and stability of sputtered perovskite solar cells can be enhanced significantly by optimizing the sputtered processes and improving the crystallization, which lay a solid foundation for further study of the preparation of perovskite solar cells by magnetron sputtering.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"6 12","pages":"5300–5306 5300–5306"},"PeriodicalIF":9.6,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142756510","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}

It explores the underlying causes and factors contributing to measurement inaccuracies. Finally, the Review puts forth strategies to overcome these challenges in three-electrode LIBs.

However, research on coevaporated perovskites with an appropriate band gap for PSTs remains limited, with lower efficiency and reproducibility than solution-processed films. Here, we present a simple approach using a thin layer of a precursor material, namely, PbI2, PbCl2, CsI, or CsCl, as a seed layer on the hole-transporting layer/perovskite interface. We find CsCl to be the optimal seed layer for our system. Perovskite single junction cells prepared with CsCl seed layer exhibit 19.6% power conversion efficiency with a band gap of 1.69 eV and improved long-term stability. We attribute the observed enhancements to the more precise and consistent incorporation of the organic precursor into the perovskite lattice during the film growth. This work demonstrates that engineering the substrate surface is crucial for achieving well-controlled growth of efficient and stable coevaporated wide-band gap perovskite solar cells.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"9 11","pages":"5639–5646 5639–5646"},"PeriodicalIF":19.3,"publicationDate":"2024-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsenergylett.4c02173","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142609558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
