摘要：
The present invention relates to a process for producing coated nanoparticles comprising a core comprising at least one first substance and at least one envelope at least partly surrounding the core and composed of at least one further substance, in a streaming system, to nanoparticles which can be produced according to this process, to nanoparticles comprising a nonporous core comprising at least one first substance and at least one porous envelope at least partly surrounding the core and composed of at least one further substance, the nanoparticles having a narrow particle size distribution, to the use of such nanoparticles in photocatalysis and to apparatus for carrying out the process.
