Polyoxometalate-directed assembly of water-soluble AgCl nanocubes Academic Article uri icon


  • Silver halide 1a and carbonate 1b nanoparticles are potent antimicrobial agents, while silver halides—indirect band-gap materials 2 —are active components of UV- and visible-light photocatalysts for pollutant degradation, 3a H 2 evolution, 3b and water oxidation. 3c,d Meanwhile, POMs have been used as functional protecting ligands for metal(0) nanoparticles, 4 and for “decorating” preformedtitania 5 and alumina-coated silica nanoparticles. 6 We now show that “out-of-pocket” association between Ag + and the defect sites of mono-vacant Keggin and Wells-Dawson ions can be used to control the formation of POM-protected AgCl nanocrystals in water, the first POM-directed synthesis of a binary-element nanocrystal … Mono-vacant derivatives of plenary Keggin and Wells-Dawson ions are polydentate ligands for main-group, transition metal, lanthanide and actinide cations. 7 The defect, or mono-vacant, anions are …
