Abstract
This invention relates to a process for the preparation of surface-functionalised metal oxide, metal sulphide, metal selenide or metal telluride nanoparticles, a process for the preparation of a composite material comprising such nanoparticles, nanoparticles and a composite material produced thereby, the use of such nanoparticles in catalysis and a catalyst comprising such nanoparticles.
Claims30
A process for the preparation of surface-functionalised metal oxide or metal chalcogenide nanoparticles, the process comprising:
- (a) providing a precursor mixture comprising a first organometallic precursor comprising a metal centre M and one or more hydrolysable organic ligands Ra, and a source of a non-hydrolysable ligand X, wherein the molar loading, [X]/[M], within the precursor mixture is from 0.001 to 0.4;
- and
- (b) exposing the precursor mixture to H2E, wherein E is O, S, Se or Te, to produce surface-functionalised metal oxide or metal chalcogenide nanoparticles.
