Abstract:
1. A nitrogen-free ozone generator system, comprising: a first electrode; a second electrode which is opposite to the first electrode and forms a discharge region having a gap; raw material gas supply means for supplying oxygen as a raw material gas; and a catalytic material which is provided on a dielectric or an electrode in the discharge region and contains a photocatalytic material with a band gap energy of 2.0 eV to 2.9 eV, wherein, when an AC voltage is applied between the first electrode and the second electrode from a power supply to produce a discharge in the discharge region, and the oxygen is supplied from the raw material gas supply means to the discharge region, then discharge light having a wavelength in a range of 428 nm to 620 nm irradiates the catalytic material from the discharge, the catalytic material is excited to dissociate the oxygen passing through the discharge region into oxygen atoms, gas pressure of the discharge region through which the oxygen passes is kept at 0.1 MPa to 0.4 MPa, and the oxygen and the oxygen atoms are subjected to a bonding process to generate ozone.
