ChemCatChem. Photo Catalytic Oxidation (PCO) is an advanced process by which volatile organic compounds (VOCs), bacteria, mold and fungus is destroyed by incorporating photon and ultraviolet (UV) energy activating a catalyst creating photo catalytic oxidation (PCO). Photocatalytic oxidation (PcCOD) is an interesting substitute for wet digestion of organic compounds. It offers several advantages such as easy operation, high efficiency, less energy consumption, and minimal secondary pollution.

A lamp life indicator displays to inform you of when the lamp requires replacing (14,000 hours Photocatalytic oxidation has demonstrated feasibility to remove toxic VOCs and formaldehyde from indoor environments. The technique is highly-chemical stable, inexpensive, non-toxic, and capable of removing a wide variety of organics under light irradiation. Photocatalytic oxidation (PCO) is achieved when you combine UV light rays with a TiO2 coated filter. TiO2 refers to Titanium Oxide.

Photocatalytic oxidation destroys microbes, volatile organic compounds (VOCs), and photocatalytic oxidation 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. What is Photocatalytic Oxidation? At Genesis Air, we utilize state-of-the-art technology to reduce airborne particles responsible for poor air quality. We achieve outstanding results by using an advanced process called photocatalytic oxidation. 2017-04-01 Photocatalytic oxidation has demonstrated feasibility to remove toxic VOCs and formaldehyde from indoor environments.

Photocatalytic Oxidation This process is a combination of photo-oxidation based on the effect of UV radiation and catalytic oxidation. It is mainly used in environments that are burdened with a high quantity of odorous and organic substances that are hard to decompose (oxidize). Photocatalytic TiO2 (aka PCO or photocatalytic oxidation – the light activated reversal of photosynthesis) is a 45 year old technology that has been the subject of 9,000+ patents and 34,000+ scientific articles. Widely studied for its potential to improve environmental remediation and infection control, there have 2021-02-04 Air treatment by Photocatalytic Oxidation (PCO) PCO in air purification involves contaminant-laden gas and a photocatalyst, usually in immobilised forms. Below is a summary of the advantages of photocatalytic air treatment: Easy generation of photocatalyst.
