“…60 A practical example of how uranyl may behave in the environment is exemplified in the degradation of the dye Rhodamine B, RhB, which is often used as a "model" organic pollutant. 103 Recent work has shown that when supported by salen or derivatized catecholate ligands, uranyl ions may assist in the photodegradation of herbicidal viologen-type pollutants. The complexes tested as photocatalysts for RhB destruction were either salicylidene-α-hydroxy acids ([UO 2 (L)(solv)] (solv = THF (245) or C 2 H 5 OH (246)), or geometric isomers suggested by the authors to result from the reaction between two asymmetric catecholamides and uranyl nitrate, "[UO 2 (L)]• 2H 2 O" (247)); in both cases the uranyl-containing catalysts are poorly defined.…”

The uranyl ion, [UVIO2]2+, possesses rigorously trans, strongly covalent, and chemically robust U-oxo groups. However, through the use of anaerobic reaction techniques, both one- and two-electron reductive functionalization of the uranyl oxo groups has been discovered and developed. Prior to 2010, this unusual reactivity centered around the reductive silylation of the uranyl ion which entailed conversion of the oxo ligands into siloxy ligands and reductive metalation of the uranyl oxo with Group 1 and f-block metals. This review surveys the large number of new examples of reductive functionalization of the uranyl ion that have been reported since 2010, including reductive borylation and alumination, metalation with d- or f-block metals, and new examples of reductive silylation. Other examples of oxo-group functionalization of [UVIO2]2+ that do not involve reduction, mainly with Group 1 cations, are also covered, along with new advances in the photochemistry of the uranyl(VI) ion that involve the transient formation of formally uranyl(V) [UVO2]+ ion.

“…ZnO and TiO 2 have unique physical and optoelectrical properties because of their dual semiconducting and piezoelectric properties with a wide bandgap of 3.37 eV and 3.2 eV, respectively [ 11 ]. These materials are categorised under Generally Recognised As Safe (GRAS) materials for human consumption by the United States Food and Drugs Administration (USFDA) [ 12 , 13 ]. Owing to their remarkable properties, these materials have been widely used as potential antibacterial, anticancer, catalysis, sensor, optic, optoelectronic and energy materials [ 14 ].…”

Facile In-Situ Fabrication of a Ternary ZnO/TiO2/Ag Nanocomposite for Enhanced Bactericidal and Biocompatibility Properties

This paper presents for the first time a successful fabrication of ternary ZnO/TiO2/Ag nanocomposites consisting of zinc oxide (ZnO), titania (TiO2) and silver (Ag) nanoparticles (NPs) synthesised using Morinda citrifolia fruit (MCF) extract. ZnONPs were synthesised using the co-precipitation method, and TiO2 and Ag were introduced into the precursor solutions under microwave irradiation to obtain ZnO/TiO2/Ag nanocomposites (NCs). This material demonstrated enhanced bactericidal effect towards bacterial pathogens compared to that of the binary TiO2/Ag, Ag and TiO2 alone. In vitro cytotoxicity results of the as-synthesised ZnO/TiO2/AgNCs on RAW 264.7 macrophages and A549 cell lines revealed a negative role in cytotoxicity, but contributed astoundingly towards antimicrobials as compared of Ag alone and binary Ag/TiO2. This study shows that the resultant ternary metal/bi-semiconductor nanocomposites may provide a therapeutic strategy for the eradication of bacterial pathogens without affecting the healthy mammalian cells.
