The atomic interface between Ga-coordinated Ru and Ru achieves monometallic synergism during alkaline hydrogen evolution reaction. The turnover frequency value of A-RuGa metallene reaches 67 s at −0.1 V RHE. Meanwhile, the mass activity of A-RuGa metallene in anion exchange membrane electrolyzer reaches 5.2 A mg at 2.0 V, firstly surpassing commercial Pt/C (1.0 A mg).

In this paper, improved low-temperature performance and resistance to K poisoning were achieved by phosphorylating CeSnO. The activity tests revealed that the phosphorylated CeSnO (3 wt%P/CeSn) exhibited over 90 % NO conversion at 190–450 °C and >90 % NO conversion at 240–400 °C even after K poisoning. The mechanism of phosphorylation treatment against K poisoning was investigated by many characterizations and DFT calculation. The results showed that the phosphorylation treatment facilitated the interaction between Ce and Sn, and K interacts more preferentially with PO species. This prevents K from destroying the Ce-O-Sn structure to form a Ce-O-K structure, which in turn maintained the catalyst’s redox properties. Moreover, the phosphorylation treatment supplemented the acidity of 3 wt%P/CeSn compared with CeSnO. This effectively mitigated the reduction of acidity caused by K and ensured the adsorption and activation of NH on the catalyst surface.","PeriodicalId":516528,"journal":{"name":"Applied Catalysis B: Environment and Energy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141943016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Ru-S-TiO is highly efficient, initiating CER at only 5 mV above the E, and has shown excellent stability for over 100 hours.
