Wet-chemical production of amorphous or crystalline metal oxide nanoparticles for self-cleaning surfaces, sun blockers, semiconductor sensors and catalytic convertors.

This development allows for wet-chemical production of non-agglomerating nanoparticles (e.g. titanium oxide, zinc oxide) from metal salts. To do so, metal salts are mixed with a reaction and stability reagent. Amorphous or crystalline metal oxide nanoparticles can then be produced depending on the reaction calibration. These can be further processed during dispersion or separated from the solvent. The metal oxide nanoparticles obtained from this can be used in this form or dispersed in another solvent, e.g. water.
