GAS PHASE ENVIRONMENTAL CLEANING MODULE USING FIBROUS SELF-SUSTAINING PHOTOCATALYST AND METHOD FOR MANUFACTURING IT

PROBLEM TO BE SOLVED: To obtain a high performance gas phase environmental cleaning module by using a self-sustaining photocatalyst which can be fixed with a low density in a space without using a binder and a base material which remarkably decrease the performance of a finely powdered photocatalyst to construct a practical energy-minimum type environmental cleaning system. SOLUTION: The high performance gas phase environmental cleaning module which can be used for constructing the practical energy-minimum type environmental cleaning system without using a binder and base material is a module in which the self-sustaining photocatalyst is filled in a space with a low density and as a photocatalyst which can be fixed with a low density in the space, a fibrous photocatalyst in which titania is a main ingredient is used. Such the module as this is manufactured through the first process wherein the fibrous photocatalyst in which titania is the main ingredient, and if circumstances require, SiO&d2&X is incorporated to make it flexible and the second process wherein the fibrous photocatalyst is filled with a low density.
