Embodiment Construction
[0055] Objects and advantages of the present invention can be more fully understood from the ensuing detailed description when read in conjunction with the accompanying drawings.
[0056] When a certain intensity of light emitted by an ultraviolet or visible light source 1 irradiates the catalyst 3 loaded on the electrode 2, the electrons in the valence band (Valence band) jump to the conduction band (Conduct band), and electrons and holes are generated, 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, breaking the bonds of organic pollutants to degrade them, and finally generate carbon dioxide and water.
[0057] When the photoelectric catalytic reactor is used for gaseous fluids, it includes:
[0058] The cathode 4 with reducing properties and the anode 5 with oxidation properties,...
