Disclosed is a nanocatalyst-type nanoscale composition including a nanoparticle semiconductor, plasmonic metal nanoparticles and an organic photosensitiser of the carbo-mer type. Also disclosed is a method for producing such a nano-catalyst. Also disclosed is use of the nanocatalyst for photoelectrolysis, in particular, for the photoelectrolysis of water, as well as to a power source including the nanocatalyst.

Three-part nano-catalyst and use thereof for photocatalysis

The present invention relates to a 'safety-by-design' method for the preparation of nanoparticles, to a method for the preparation of a nanocomposite material, and to the use of a direct liquid injection device so as to prepare nanoparticles or nanocomposite materials in a 'safety-by-design' process.

Process for the preparation of nanoparticles

A process for preparing a composition of mixed crystalline particles from columns 13-15 in which a liquid solution is produced by solubilization in a non-aqueous solvent medium of at least one first precursor chosen from coordination complexes including at least one element E1 from column 13, then the liquid solution is brought into contact with at least one second precursor chosen from the hydrides of at least one element E2 from column 15.

Process for preparing a compostion of mixed particles containing elements from columns 13 and 15

A method for preparing a composition of metal nanocrystals from at least one organometallic precursor in a solvent medium in the presence of a PEG ligand, including a carbon chain, at least one end of which is functionalized by a coordination grouping including at least one hetero atom, and having at least one [OCHCH]grouping, n being an integer higher than 1, so as to be soluble both in the solvent medium and in water. The water-compatible and organic-compatible composition of metal nanocrystals thus obtained is also described.

Method for preparing an organic-compatible and water-compatible composition of metal nanocrystals, and resulting composition

A method for preparing a composition of metal oxide nanocrystals from at least one organometallic precursor in an aprotic solvent in the presence of at least one PEG ligand including a carbon chain having at least one end functionalized by a coordinating group containing at least one heteroatom, and at least one [&#x2014;OCHCH], group, such that it is soluble in both the aprotic solvent medium and in water. The resulting water-compatible and organocompatible composition of metal oxide nanocrystals is also described.

Method for preparing a water-compatible composition of metal oxide nanocrystals and the water-compatible composition obtained

The invention relates to a method for the preparation of a composition of nanoparticles of at least one crystalline metal oxide from at least one organometallic precursor. One precursor(s) which can react spontaneously to oxidation is selected; a liquid solution of the precursor(s) is produced in a solvent non-aqueous medium, and the liquid solution is placed in contact with at least one oxidant in adapted reactional conditions in order to directly result in the production of nanoparticles of crystalline metal oxide(s). The invention also relates to a composition of nanoparticles obtained in the form of a colloidal liquid solution.
