Abstract

A self actuated photocatalyst $Weltouch^{(R)}$ used to the remove the odor gases generated in the foaming process of shoes insole was prepared by sol-gel method and studied its property. Specially, with mixing $Weltouch^{(R)}$ in the foaming process of shoes insole, the physical functionality such as specific gravity, hardness, elongation, compression set was studied. The physical functionality of shoes insole was no variation by added $Weltouch^{(R)}$. The odor gases generated in the foaming process of shoes insole was detected to be reduced to 60~80% by self actuated photocataylst $Weltouch^{(R)}$ even in the dark conditions, which was observed for both anatase and rutile phase.
