- Plasma-Photo Catalyst Reactor for Removal of Ammonia Packing Material coated with Photo Catalyst for the same Reactor and Preparation of the same Packing Material

摘要

The present invention provides a plasma-photocatalyst ammonia removal device for removing ammonia from air, a photocatalyst-coated filling material used therefor, and a manufacturing method thereof. A plasma-photocatalyst reactor for ammonia removal provides perovskite ceramic coated with titanium dioxide in a plasma reactor using a cylinder metal housing as one electrode and a metal wire or a metal rod located at the center of a cylinder as another electrode. A manufacturing method of a perovskite ceramic filling material coated with titanium dioxide comprises: a step a) of filling a plasma reactor with a perovskite ceramic to be coated with titanium dioxide; a step b) of coating the perovskite ceramic with titanium dioxide by generating a plasma while introducing titanium ethoxide and oxygen or air as a precursor of titanium dioxide into the plasma reactor; and a step c) of heat-treating the titanium dioxide-coated perovskite ceramic at 300 to 500°C for 1 to 5 hours. The present invention can easily manufacture titanium dioxide-coated perovskite ceramic filling material.
