Photocatalyst Functions(3)

Definition of titanium dioxide

Best UV room sterilizer enjoys following specifications. Rated power: 120WRated. Voltage: 110V-220V. UV-C Lamp power: 90W. Net weight: 5.1kg. Titanium dioxide is an inert substance with stable chemical properties, which can continuously exert antibacterial effects under light conditions. It mainly has three crystal forms: anatase, rutile and brookite. Studies have shown that anatase is the most efficient photocatalyst, while rutile is less active. Surprisingly, mixtures of anatase and rutile, or when anatase was doped with metals such as sulfur, anion, or silver, showed more efficient photocatalysis than 100% anatase, And the virus inactivation effect is also better. In addition, compared with bulk titanium dioxide materials, titanium dioxide nanoparticles have better performance in inactivating pathogens. The researchers collectively refer to those photo-semiconductor materials with photocatalytic function represented by nano-scale titanium dioxide as photocatalysts.

The work of photocatalyst

When UV light hits titanium dioxide, incident photons activate the production of reactive oxygen species. The TiO2 photocatalytic surface is in direct contact with the cell wall, causing oxidative damage to the cell wall.

Photocatalyst sterilization technology has a good bactericidal effect on a variety of microorganisms, and can widely kill gram-negative and gram-positive bacteria, fungi (single cell and filamentous), protozoa, algae, mammalian viruses and phage. Best UV room sterilizer is wall-mountable.

Titanium dioxide has the potential to inactivate antibiotic-resistant bacteria as the incidence of antibiotic-resistant bacterial infections has risen sharply in recent decades, making it one of the most important issues in public health. The researchers found that UVA-activated titanium dioxide can be used to inactivate methicillin-resistant Staphylococcus aureus (MRSA), multidrug-resistant Acinetobacter baumannii (MDRAB), and vancomycin-resistant Enterococcus in suspension. Titanium dioxide was able to effectively reduce the amount of drug-resistant microorganisms in suspension when UVA was present.
