The pore size difference prevents TRZ from entering the HOF-K while allowing TRZ to selectively insert into the larger-pored HOF-C to form HOF-C-TRZ. The donor-acceptor (D-A) structure formed in HOF-C-TRZ enhances its photoelectric response and exhibits exceptional uranium reduction under visible light irradiation. This study provides an effective strategy for pore size regulation of HOFs and opens up new ideas for the development of advanced uranium photocatalysts.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"30 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142825462","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}

Hydrogen can be produced from renewable sources and may play a crucial role in the zero-carbon economy, which is regarded as a promising alternative to fossil fuels. Currently, hydrogen production via water electrolysis still relies on high-purity water, while seawater electrolysis gets benefit from the abundance of seawater, which can be particularly beneficial for water-scarce countries, and deep-sea applications, such as floating platforms or islands. However, it faces several challenges, such as the impurities in seawater, the harsh marine environment, and unpredictable costs. Ongoing researches and development efforts are focused on addressing these challenges through innovative solutions, including the design of robust electrocatalysts, the development of smart integrated structures, and the exploration of innovative coupled systems. In this review, big progresses mentioned above aim to improve the efficiency of seawater electrolysis are briefly discussed, and the challenges and prospects are provided.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"5 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820720","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}
