IONIZER

摘要

Provided is an ionizer. In an embodiment, concaves-convexes are formed on a surface of a substrate, one or more electrodes for generating a positive ion or a negative ion is formed, and the concaves-convexes are coated with photocatalyst. The electrode is formed on a surface opposite to the surface on which the concaves-convexes are formed, and two or more substrates are disposed in line at an interval while the electrode and the concave-convex face each other. The ionizer according to another embodiment includes a 3D substrate having a polygonal pillar shape in which polygonal planes are perforated; an electrode unit including one or more electrodes formed on at least one inner surface of pillar planes forming the polygonal pillar to generate a positive ion or a negative ion; and a coating part in which an inner surface facing the pillar plane with the electrode unit is coated with photocatalyst.
