IMMOBILIZED PHOTOCATALYST AND METHOD FOR IMMOBILIZING PHOTOCATALYST

摘要

PURPOSE: To produce an immobilized photocatalyst having high catalyzing ability as well as high durability and to provide a method for immobilize a photocatalyst. ;CONSTITUTION: A powdery photocatalyst is immobilized on a support with an alkali metal silicate as a binder to obtain the objective immobilized photocatalyst whose alkali metal silicate content is 6-32 pts.wt. per 100 pts.wt. of the powdery photocatalyst. An aq. suspension contg. 100 pts.wt. powdery photocatalyst and 6-32 pts.wt. alkali metal silicate is applied to a support and hardened to immobilize the photocatalyst.;COPYRIGHT: (C)1996,JPO
