Description

technical field

[0001] The invention relates to a photoelectric synergistic catalytic reactor, in particular to a photoelectric catalytic reactor and a degradation method for degrading organic pollutants. Background technique

[0002] There are harmful volatile organic compounds such as formaldehyde released from decorative materials in homes, entertainment places (such as dance halls, etc.), automobiles, etc., as well as volatile sweat odors of organisms and harmful microbial bacteria and viruses. These harmful gases not only damage people's physiological functions, but also increase the chance of spreading diseases. Therefore, solving the problem of indoor air pollution is particularly important for people's health.

[0003] The scented air purifiers currently used just cover up the unpleasant smell of organic matter, but cannot eliminate its harmfulness.

[0004] Another method is adsorption, such as using activated carbon particles to adsorb organic molecules in the gas...

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,...
