SINTESI ONE-POT DI NANO CRISTALLI 1D, 2D, E 0D DI CALCOGENURI DI TUNGSTENO E MOLIBDENO (WS2, MOS2) FUNZIONALIZZATI CON AMMINE E/O ACIDI GRASSI A LUNGA CATENA E/O TIOLI

摘要

The present invention describes a new synthetic strategy that permits to produce 2D 1D, e OD hybrid organic-inorganic nanocrystals of tungsten/molybdenum chalcogenides. The innovative chemical approach is based on the thermal decomposition of a molecular precursor containing both metal and sulphur, in a mixture of long chain amines and/or fatty acids and/or long chain thiols. By the control of reaction conditions is possible to address the synthesis can be driven towards the formation of nanosystems with different morphologies such as sheets, particles, rods, tubes.
