    摘要: 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.

    摘要: A process for preparing formaldehyde by oxidative dehydrogenation of methanol comprises passing a gas mixture (i) comprisinga) from 0.1 to 50% by volume of methanol,b) from 0.1 to 30% by volume of oxygen,c) from 0 to 50% by volume of nitrogen oxide andd) from 0 to 60% by volume of water at from 150 to 800.degree. C. through a phosphorus-doped silver catalyst fixed bed (a) and applying from 0.01 to 100 ppm by weight of phosphorus, based on the phosphorus-doped silver catalyst fixed bed, in the form of a finely divided phosphorus compound having a melting point or decomposition temperature of more than 500.degree. C. (phosphorus compound P) to the phosphorus-doped silver catalyst fixed bed (a) per kg of methanol which is passed through in the form of the gas mixture (i) per cm.sup.2 of the cross-sectional area of the phosphorus-doped silver catalyst fixed bed (a).
