Fujitsu developed a photocatalytic material called titanium apatite in which a part of calcium ions in apatite crystals are substituted by titanium ions and which has similar photocatalytic properties as titanium dioxide. It also has the characteristics of apatite which is a bone component so that it excels in absorbing organic matter. As a result titanium apatite can absorb and capture microbes and viruses to inactivate and decompose them. It also has an anti-allergenic effect.
Photocatalytic titanium apatite has similar photocatalytic properties of the conventionally used photocatalyst titanium dioxide. Has the same structure as hydroxyapatite which is included in bones and is highly effective at adsorbing organic materials. Shows inactivating effect against viruses microbes and allergens even in dark condition. Can be formed into thin films by coating on various substrates including glasses. Can be used even when mixed into organic materials such as fibers or plastics (acts only for pollutants absorbed on surfaces does not degrade substrate materials); non-disclosure
