Abstract:
The invention relates to a spray pyrolysis method characterized in that it is used in the synthesis of nanoparticles with a closed structure of metal chalcogens having a lamellar crystalographic structure of general formula MaXb, wherein M represents a metal and X represents a chalcogen, a and b represent the respective proportions of metal and chalcogen, and in that it comprises pyrolysis of a liquid aerosol obtained from a solution of at least one metal precursor (M) and a chalcogen (X), or at least one precursor of said metal (M) and at least one precursor of said chalcogen (X) dissolved in a solvent, said solution being atomized into fine droplets in a suspension in a vector gas.
