SYNTHESIS OF NANOPARTICLES WITH A CLOSED STRUCTURE OF METAL CHALCOGENS HAVING A LAMELLAR CRYSTALOGRAPHIC STRUCTURE AND USES THEREOF

Production of nanoparticles (A) of metal chalcogenides having a lamellar structure involves pyrolysis of a liquid aerosol obtained by spraying a solution of precursor(s) of the metal and chalcogen (or separate precursor(s) of the metal and of the chalcogen) in a solvent as fine suspended droplets in...

More Information
Summary:Production of nanoparticles (A) of metal chalcogenides having a lamellar structure involves pyrolysis of a liquid aerosol obtained by spraying a solution of precursor(s) of the metal and chalcogen (or separate precursor(s) of the metal and of the chalcogen) in a solvent as fine suspended droplets into a carrier gas. (A) in the form of in the form of 'nanoboxes' are new. Production of nanoparticles (A) of metal chalcogenides having a lamellar structure, of formula M aX b (I), involves pyrolysis of a liquid aerosol obtained by spraying a solution of precursor(s) of M and X (or precursor(s) of M and precursor(s) of X) in a solvent as fine suspended droplets into a carrier gas. M : metal; X : chalcogen; a, b : proportions of M and X respectively. An independent claim is included for nanoparticles (A') of metal chalogenides of formula MX 2 (I'), in the form of 'nanoboxes', i.e. generally hollow, close, rectangular, right-angled parallelepipedes.
