Patent ID: 8075844

Claim:
An ozone generator comprising: a first electrode; a second electrode facing the first electrode and defining a discharge area in which an electrical discharge takes place in response to application of an AC voltage across the first and second electrodes; a first raw material gas supply unit for supplying oxygen as a first raw material gas; a photocatalytic material or a material transforming into a photocatalyst in response to the electrical discharge, located in a dielectric substrate that is located in the discharge area or that is located in the first electrode, for absorbing light in a specified wavelength range; and a second raw material gas supply unit for supplying a second raw material gas which is excited by the electrical discharge and generates excited light to excite the photocatalytic material or the material transforming into a photocatalyst to accelerate dissociation of the oxygen, wherein the AC voltage applied across the first electrode and the second electrode is supplied by a power supply, and quantities of the first and second raw material gases are supplied by the first and second raw material gas supply units to a space where the electrical discharge is generated in the discharge area and in which ozone is generated in response to the electrical discharge.
