METHOD FOR REFORMING VISIBLE LIGHT-RESPONSIVE PHOTOCATALYST, REFORMED VISIBLE LIGHT-RESPONSIVE PHOTOCATALYST, METHOD FOR DECOMPOSING ORGANIC MATTER USING PHOTOCATALYST, AND APPARATUS FOR CARRYING OUT REFORMING

摘要

PROBLEM TO BE SOLVED: To provide a method for increasing the speed of decomposition of an aromatic compound such as toluene to carbon dioxide in the case of decomposition removal of the aromatic compound by using a visible light-responsive photocatalyst containing a tungsten compound such as tungsten oxide or a tungsten compound mixed with a co-catalyst and radiating visible light.

SOLUTION: The speed of complete decomposition of organic matter such as toluene to carbon dioxide under visible light radiation is increased by using a visible light-responsive photocatalyst containing a tungsten compound such as tungsten oxide or a tungsten compound mixed with a co-catalyst and causing the catalytic reaction in a state that the surface of the photocatalyst is reformed by adding water or controlling humidity.
