A method for simply decomposing and disposing organic substances while preventing occurrence of toxic substances, which method is directed, firstly, to a technique wherein photocatalyst powder is applied from the upper side with liquefied organic substances, and the photocatalyst powder is heated to between 50 and 400°C, secondly to a technique wherein photocatalyst powder is contacted with gaseous organic substances while the photocatalyst powder being heated to between 50 and 400°C, thirdly to a technique wherein an organic substance to be decomposed is introduced, in a state of gas, liquid or solid, into a suspension of photocatalyst's finely divided particles and is heated in a range of temperatures between 50 and 100°C, and fourthly to a technique wherein organic substances are decomposed at two or more stages.

摘要:
Titanium oxide catalyst has been given attention recently as oxidizing catalyst showing the catalytic effect at normal temperatures and has been put into practical use. The conventional ones are finely divided powder in nm unit in relation to catalytic efficiency, so that the powder is quite fine and it is very much hard to handle them. Granulating the finely divided powder for easy handling has been proposed but provides merely poor catalytic efficiency. The present invention provides shaped or granulated titanium oxide that is ensured of volume to some extent and keeps catalytic efficiency within the range of possibility.
