The introduction of these small molecules enhances the visible light absorption range and redistributes the charge density. Combining DRS, KPFM, and DFT results, it is revealed that the strong built-in electric field and the effective spatial separation of redox sites contribute to the directional charge separation and migration for superior photocatalytic H2 evolution. The FCN shows robust photocatalytic stability for generating H2 as long as 23 h. It is hoped that this catalyst, produced by one-step polymerization with a high internal driving force for charge separation, will provide a solid basis for improving hydrogen production performance in the future.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"45 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143026827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, huge volumetric expansion occurs during lithiation. Moreover, the loss of Li+ ions during cycling remains a challenge. Here, we develop a dual-porous carbon-coated Si (DP Si/SiOx@Li-C) using pore-forming agent and lithium source to create controllable pores in carbon layer of porous Si/SiOx, and supply Li+ to the anode. The dually porous structure accommodates the volumetric change and enables rapid ion transfer, while supplying abundant Li+ ions. The DP Si/SiOx@Li-C anode exhibits a stable capacity of 809.8 mAh g-1 after 100 cycles at 0.1 A g-1; with a decay rate of only 0.093% per cycle, and a Coulombic efficiency exceeding 99.2% when cycling 350 times at 0.5 A g-1. These findings provide a new strategy for developing stable and easy-preparing Si anodes for Li-ion batteries.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"62 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143027024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
