Iron-based layered double hydroxides (LDHs) obey to the general chemical formula [MII(1-x)MIIIx(OH)2]x+. [(x/n) An-, m H2O]xand contain a minimum of 50 % of iron, i.e. FeII or FeIII, in the cationic sheets. As LDHs contain FeII species, these are interesting minerals for several applications such as the reduction of anionic pollutants or the degradation of organic pollutants. They are mostly pr...
We report a sono-Fenton strategy to mediate the supramolecular assembly of metal–phenolic networks (MPNs) as substrate-independent coatings using phenol and phenyl derivatives building blocks. The process is initiated from generation hydroxyl radicals (.OH) high-frequency ultrasound (412 kHz), while metal ions synergistically participate in production additional .OH for hydroxylation/phenolatio...
The association process between the tetracycline (TC) antibiotic molecule and Keplerate-type nanocluster polyoxometalate (POM) {Mo72Fe30} was studied in aqueous solution. novel supramolecular ensemble {Mo72Fe30}@TC12.5 produced, its composition structure were revealed by means of elemental analysis (C, N, H) vibrational spectroscopy (IR Raman). Based on spectral data, POM structure’s integrity ...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
