Photocatalytic exhaust gas purification device for IC engines to remove pollutants comprises photocatalyst consisting of catalytically active substance fixed to carrier and radiation source

摘要

A photocatalytic exhaust gas purification device comprises a photocatalyst (18) consisting of a catalytically active substance fixed to a carrier and a radiation source (24) for bombarding the substance with electromagnetic radiation. Preferred Features: The radiation source is integrated into the photocatalyst. The radiation source is a pressure discharge lamp, especially a high pressure discharge lamp or a low pressure discharge lamp. The radiation source is held in a flow channel. An inner diameter of the flow channel is larger than an outer diameter of the radiation source.
