Abstract: A plasma coating method for coating particulate matter, including the steps of: a) providing a low-temperature atmospheric plasma jet from a plasma gas outside of the reaction chamber; b) inserting a precursor into the plasma jet, thereby obtaining a plasma coating flow comprising an excited precursor, followed by injecting the plasma coating flow comprising the excited precursor in the reaction chamber, and c) subjecting particulate matter to said plasma coating flow comprising said excited precursor, thereby obtaining particulate matter comprising an at least partial coating. a coating reactor apparatus and a system involve the plasma coating method.
