The structure determined by single-crystal X-ray diffraction revealed two dimensional extended assemblies based on connectivity of Cd2+ ions with two ligands. The presence of one free carboxylic acid groups of each BTCH ligand and one non-bonded pyridine ring of each L ligand makes the two-dimensional layer structure stabilized through the hydrogen bond interactions. The compound has been characterized by powder X-ray diffraction, Fourier transform infrared (FTIR) spectroscopy and thermogravimetric analysis (TGA). Aqueous dispersion of compound 1 showed emission at 400 nm upon excitation at 300 nm. The compound 1 also exhibited photoluminescence-based sensing behaviors towards Fe3+, Al3+ and Cr3+ ions in aqueous medium based on luminescence quenching effect. However, photoluminescence studies in presence of other common metal ions showed either negligible quenching effect or moderate to low turn on effect for Ni2+, K+, Zn2+, Cd2+ Cu2+, Ca2+, Mn2+, Na+, Co2+, Fe2+, Pb2+, Mg2+ in aqueous.

Thermogravimetric analysis (TGA) and FT-IR spectroscopy confirmed efficient CO2 adsorption with a maximum adsorption capacity of 0.020 mmol/g and a desorption rate of 20 %. The Photocatalytic CO2 reduction mechanism was investigated, demonstrating that MOF@VP facilitates the conversion of CO2 to formic acid via electron transfer with the TEOA (Tri-ethanolamine) as a sacrificial reagent. Cyclic voltammetry revealed enhanced electrochemical activity in the presence of CO2 further supporting the catalytic reduction mechanism. GC–MS analysis confirmed the formation of formic acid as a dominant product. The stability and Regeneration tests showed that the MOF@VP retained its efficiency and thermal stability after multiple cycles. These findings highlight the potential of using MOF@VP as a robust and efficient catalyst for CO2 reduction, addressing key challenges in catalyst performance and longevity.</div></div>","PeriodicalId":13599,"journal":{"name":"Inorganica Chimica Acta","volume":"579 ","pages":"Article 122586"},"PeriodicalIF":2.7,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143376715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
