METHOD OF STICKING/FIXING TITANIUM DIOXIDE TO THREE- DIMENSIONAL AND TWO-DIMENSIONAL STRUCTURES AND CONTACT METHOD

摘要

PROBLEM TO BE SOLVED: To produce a photocatalyst contact material by fixing titanium dioxide fine powdery material onto the surface of a curved filament of a thermoplastic polypropylene or the flat surface of a two-dimensional structure with a binder or the binder and cement so that the titanium oxide fine powdery material is exposed, and to decompose harmful substances contained in the natural atmosphere by strong oxidation power of the photocatalytic reaction. ;SOLUTION: A method of producing the photocatalyst contact material comprises sticking/fixing titanium dioxide fine powdery material onto the surface of a three-dimensional permeable contact material composed of curved filaments of a thermoplastic polypropylene or the surface of an inorganic two-dimensional structure. The contact method comprises bringing the natural atmosphere or the like into contact with the photocatalyst contact material and oxidizing/decomposing organic compounds, organic chlorine compounds, volatile hydrocarbons, NOx, SOx, oil content, exhaust gases from automobiles, or the like contained in the atmosphere by the photocatalytic reaction of the titanium dioxide.;COPYRIGHT: (C)2001,JPO
