The U and U-N MOFs are synthesized via a convection solvothermal method, and their structural, optical, and electrochemical properties, along with their performance in the Oxygen Evolution Reaction (OER) and Hydrogen Evolution Reaction (HER), are comprehensively characterized. The XRD patterns confirm the high crystallinity of both U and U-N, while FTIR spectra indicate the presence of typical functional groups in these MOFs. The UV-Vis absorbance spectra reveal a red shift in U-N compared to U, signifying a reduced band gap energy due to amino functional groups. TEM images display distinct particle sizes and morphologies with U-N exhibiting agglomerated particles and a narrower size distribution. BET analysis demonstrates the porous nature of both MOFs, with U exhibiting a greater surface area. Electrochemical studies reveal that U-N exhibits superior OER activity, characterized by lower overpotential, and a lower Tafel slope, as well as exceptional stability under prolonged electrochemical conditions. The amine (NH₂) groups in U-N are the primary factor contributing to its enhanced OER performance. Additionally, U-N displays a reduced band gap energy, promoting improved catalytic activity and sustained performance. On the other hand, the U MOF demonstrates promising HER activity, maintaining effective current density for a significant duration, albeit indicating the need for enhancements to ensure prolonged stability. The CV and Nyquist plots further reveal that the U-N MOF possesses a larger electrochemical surface area, higher sensitivity, and enhanced conductivity, attributed to the presence of amino (NH₂) groups, leading to more efficient charge transport within the material. Overall, this comparative study underscores the potential of U-N as a highly efficient electrocatalyst for water-splitting applications, offering valuable insights for the design and development of advanced MOF-based electrocatalysts.</div></div>","PeriodicalId":393,"journal":{"name":"Molecular Catalysis","volume":"578 ","pages":"Article 115025"},"PeriodicalIF":3.9,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619479","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}
