Photocatalytic oxidation

Inside of blue dots line is coated with TiO2. We performed the photocatalytic oxidation of arsenite in aqueous TiO 2 suspension and investigated the effects of pH, dissolved oxygen, humic acid (HA), and ferric ions on the kinetics and mechanisms of arsenite oxidation. Arsenite oxidation in UV-illuminated TiO 2 suspension was highly efficient in the presence of dissolved oxygen. Volatile organic compounds (VOCs) are the major group of indoor air pollutants, which significantly impact indoor air quality (IAQ) and influence human health. Photocatalytic oxidation (PCO) is a cost-effective technology for VOCs removal, compared with adsorption, biofiltration, or thermal catalysis method. Development of active photocatalyst systems is crucial for the PCO reaction.

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.

Organic electronic materials for hydrogen peroxide production

The process consists of passing the contaminated air over an illuminated catalyst (usually titanium dioxide, Ti02) at ambient temperatures. ASHRAE Denver – April 15, 2011 Photocatalytic Oxidation The Quantum Physics behind .

Photocatalytic oxidation is now mainly used to treat water and air. Because it can decompose pollutants Aug 19, 2014 Photocatalytic oxidation (PCO) is achieved when you combine UV light rays with a TiO2 coated filter. TiO2 refers to Titanium Oxide. This paper presents a methodology for the evaluation of the intrinsic photocatalytic oxidation (PCO) kinetics of indoor air pollutants.

Relies on unsafe oxidisers : N/A: N/A: N/A Viruses remain in air until passed through unit or by technology Process weakens further away from target: N/A: N/A Photocatalytic oxidation can also inactivate infectious microorganisms which can be airborne bioterrorism weapons, such as Bacillus anthracis (Anthrax) [46–48]. A photocatalytic system was investigated by Knight in 2003 to reduce the spread of severe acute respiratory syndrome (SARS) on flights [ 49 ], following the outbreak of the disease.

It offers several advantages such as easy operation, high efficiency, less energy consumption, and minimal secondary pollution. Photocatalytic Oxidation (PCO) is a very powerful air purification technology and has the ability to destroy particles as small as 0.001 microns (nanometer) whereas HEPA filters can only filter particles as small as 0.3 microns. 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?

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.

The photocatalytic oxidation (PCO) process involves combining ultraviolet light irradiation with a titanium dioxide coated filter. Here’s how the titanium dioxide catalyst in an air purifier breaks apart molecules of air pollution: When UV light shines on the titanium dioxide, electrons are released at its surface.
