An active oxidation and purifying system is provided to increase or maximize the rate of photocatalytic oxidation and ambient air purification capacity by providing both direct ultraviolet (UV) light and reflected UV light directed to the surface and apertures of active cell panels coated with a photocatalytic material. In one example, the active cells also include a plurality of apertures
The Photocatalytic Oxidation process combines UV irradiation with a substance (catalyst) titanium dioxide (TiO2) which results in a reaction that changes malignant contaminants into water, carbon dioxide and detritus.
Filtration can be an effective means of controlling the aerobiology of indoor air. Filters trap particles that over time incubate airborne organisms – including pathogens. The fact is filters deactivate nothing. And, they create a disposal problem, and Utilizing the strong oxidation strength of hydroxyl radical, photocatalytic oxidation can effectively disinfect, deodorize, and purify air, water, and different surface area.

A comprehensive review of the UV-TiO2 photocatalytic oxidation process was conducted with an insight into the mechanism involved, catalyst TiO2, irradiation sources, types of reactors, comparison between effective modes of What is Photocatalytic Oxidation? Oxidative decomposition means that if titanium oxide is exposed to light, organic substances on its surface will be broken down by oxidation, eventually forming carbon dioxide and water. The role of primary active species (ecb−, hvb+, •OH, HO2•, O2•−, and H2O2) during photocatalytic degradation of paracetamol (acetaminophen) using TiO2 catalyst was systematically investigated. Hydroxyl radicals (•OH) are responsible for the major degradation of paracetamol with a second-order rate constant (1.7 × 109 M−1 s−1) for an •OH−paracetamol reaction.

We achieve outstanding results by using an advanced process called photocatalytic oxidation. While some air cleaning applications simply filter the air and trap pollutants, photocatalytic oxidation break down these airborne contaminates. What Makes Us Different?
The Air Sniper features four zones of Ultraviolet (UV-C) light that is multiplied using our Photocatalytic Oxidation (PCO) elements. This ensures that over 99.9% However, the usage of hydrgen peroxide adds to the cost of ozonation alone. Photocatalytic oxidation processes. Advanced Oxidation Processes can be Due to the efficient mineralization of organic compounds; advanced oxidation process is gaining relevance in the industries. The Photochemical AOP is the The air purification process of using photocatalytic oxidation often works by “ attacked” by free hydroxyl radicals and super-oxide ions, (created by UV light and photocatalysts Freshome coating is coated on indoor furniture, walls, ceilings, etc . The formed activated oxygen is strong enough to oxidize and decompose The MCI TiO2 technology is also effective in oxidizing and reducing chemical gasses, volatile organic compounds, smoke and odors to improve the air quality The PCO process creates a powerful oxidising agent inside the air purifier. This destroys garbage odours and pathogens, returning clean air into the room.
