Abstract[English]
Complexes of polyoxometalate (POM) cluster anions and nanoparticle (NP) cores, are disclosed, featuring inherent thermodynamic stability at least due to covalent bonds, which attach the POMs to the NP cores. The nanoparticles coprise a plurality of crystalline, polycrystalline or amorphous metal-oxide, metal oxyhydroxide and/or metal hydroxide compounds. The POM and NP, each independently, may comprise one, two, three or more different metal cations, particularly transition or main group metal cations. These complexes are highly soluble in water and inherently stable to oxidation and hydrolysis in a broad pH range. As such, the complexes are usfule, inert alia, as improved soluble water-oxidation catalysts and stabilizers of metastable crystals.[French]
L'invention concerne des complexes d'anions en grappe de polyoxométalate (POM) et de noyaux de nanoparticules (NP), présentant une stabilité thermodynamique inhérente au moins due à des liaisons covalentes, qui fixent les POM aux noyaux NP. Les nanoparticules se composent d'une pluralité de composés cristallins, d'oxyde métallique polycristallin ou amorphe, d'oxyhydroxyde métallique et/ou d'hydroxyde métallique. Le POM et le NP, chacun indépendamment, peuvent comprendre un, deux, trois cations métalliques différents ou plus, en particulier des cations métalliques de transition ou de groupe principal. Ces complexes sont hautement solubles dans l'eau et intrinsèquement stables à l'oxydation et à l'hydrolyse dans une large plage de pH. En tant que tels, les complexes sont utiles, entre autres, en tant que catalyseurs solubles d'oxydation dans l'eau améliorés et stabilisants de cristaux métastables.
