Optical Catalyst System for Removal of Floating Bacteria
Ohken Corporation and the National Industrial Research Institute of Nagoya have jointly developed a system (Ohken AC-2001) for the removal of floating bacteria from the air, using an optical catalyst.
With this system, air is sucked in with a fan and deodorising is achieved using a three-dimensional ceramic filter coated with titanium oxide (an optical catalyst), after which sterilisation is carried out through a honeycomb filter.
When irradiated with a light beam, titanium oxide uses oxidation reaction to remove bacteria and perform deodorisation. In the Ohken system, an ultraviolet beam generates ozone and ...
