Abstract

A variety of reactors that are arranged to treat aerosol particulates that are carried in a fluid stream passing through the reactor is described. In one aspect, the reactor includes a plasma chamber arranged to receive the fluid stream and subject particulates carried in the fluid stream to a cold plasma that has a sufficiently high concentration of reactive species to treat at least some of the particulates passing therethrough. A catalyst is provided downstream of the plasma chamber. The catalyst is arranged to enhance the conversion of reactive species that are contained in the fluid stream before the stream emerges from the reactor. In another aspect, a catalyst electrode is described. The catalyst electrode may include a catalyst material carried on an electrode. A potential may be applied to the electrode during use to attract charged species towards the catalyst. In some embodiments, the catalyst electrode includes a metal frame that serves as the conductive electrode and a catalyst material such as manganese dioxide is applied to the metal frame.
