Abstract

The invention relates to a method for producing micro-nano combined active systems in which nanoparticles of a first component are bonded to microparticles of a second component, comprising the following steps: (a) producing a low-ligand colloidal suspension containing nanoparticles of the first component, (b) adding microparticles to the colloidal suspension containing the nanoparticles or adding the colloidal suspension containing the nanoparticles to a dispersion containing the microparticles and intensively mixing so that the nanoparticles adsorb onto the microparticles, (c) separating the microparticles and the nanoparticles bonded thereto from the liquid and drying the microparticles and the nanoparticles bonded thereto.
