Abstract

The invention relates to a process for producing morphologically uniform and virtually monodisperse metal-containing nanoparticles, characterized in that the separation both in time and space of the nucleation and growth processes is achieved by regulation of the temperature and volume flows, with the reaction and particle formation preferably being initiated and carried out in a suitable microstructured modular reactor system. Modularization of the microreaction plant (micro heat exchanger, residence reactor, micromixer, etc.) allows optimal setting of the respective chemical and process-engineering process parameters and thus the preparation of virtually monodisperse and morphologically uniform nanoparticles.
