Document Type and Number:
Japanese Patent JP2004321864
Kind Code:
A
Abstract:
To provide a method for simply washing a photocatalyst filter, which has a porous ceramic carrier and a metal oxide like titanium oxide functioning as a photocatalyst supported on the carrier, without lowering photocatalytic activity.
The washing method includes a process for immersing the photocatalyst filter in an alkali washing solution containing aqueous hydrogen peroxide to bubble the surface part of the filter, a process for removing the alkali washing solution bonded to the photocatalyst filter and a process for restoring the photocatalytic function of the photocatalyst filter from which the alkali washing solution is removed.
