Embodiment Construction
[0055] The purpose and advantages of the present invention can be more fully understood from the following detailed description with reference to the accompanying drawings.
[0056] When a certain intensity of light emitted by the ultraviolet or visible light source 1 irradiates the catalyst 3 supported on the electrode 2, the electrons in the valence band transition to the conduction band, generating electrons and holes, respectively. Strong oxidizing and reducing properties, react with water vapor and oxygen in the air to generate active free radicals, such as OH groups such as OH, H, O 2 - , H, etc., they have a strong ability to react with other substances, break the bonds of organic pollutants to degrade them, and finally generate carbon dioxide and water.
[0057] When the photoelectric catalytic reactor is used for gas fluid, it includes:
[0058] Cathode 4 with reducing properties and anode 5 with oxidizing properties, solid electrolyte 6 separates cathode 4 and anode 5, ...
