What is titanium oxide?
Titanium oxide which causes photocatalytic reaction is been widely recognized for its high bactericidal action (anti-bacterial effect). Titanium oxide… • is completely harmless to humans • has strong effects only to single-celled organisms such as fungi The strong anti-bacterial effect of titanium oxide is brought out when being exposed to light (ultraviolet radiation) It means the anti-bacterial effect is caused by absorption and decomposition of toxins during the photocatalytic reaction of titanium oxide. Generally speaking, the bactericidal effect (disinfection) by titanium oxide is three times stronger than chlorination, and 1.5 times stronger than ozonation The use of titanium oxide (TiO2) has been valued in diverse fields because it is able: • to decompose NOx in exhaust gases which cause air pollution • to prevent buildings and windows from being stained and damaged by exhaust gases • to decompose VOC which causes sick house syndrome • to eliminate odor in materials for the ca
