The photocatalytic apatite composition and its production method are
disclosed. The photocatalytic apatite comprises a photocatalytic apatite
having incorporated into the apatite crystal structure thereof a metal
oxide having a photocatalytic action, such as titanium oxide, and a metal
ion having an antimicrobial property, such as a silver ion or a copper
ion. The photocatalyst apatite composition is capable of maintaining
excellent decomposition and adsorption properties for various organic
materials such as VOCs or specific adsorbing substances such as a virus
for a long time and, at the same time, expressing an excellent
antimicrobial property in a dark place as well as under daylight.
