1. A spray pyrolysis method, characterized in that it is applied to the synthesis of nanoparticles with a closed structure of metal chalcogenides having a lamellar crystallographic structure, of the general formula MaXb, in which M represents a metal and X a chalcogen, a and b representing the respective proportions of metal and of chalcogen, and in that it comprises pyrolysis of a liquid aerosol obtained from a solution of at least one precursor of a metal (M) and of a chalcogen (X), or of at least one precursor of said metal (M) and of at least one precursor of said chalcogen (X), dissolved in a solvent, said solution being atomized into fine droplets in suspension in a carrier gas.
