A coated substrate, especially a glass substrate, such coated substrate having high photocatalytic activity and low visible light reflection as well as being highly abrasion resistant. Preferably, the coating is a titanium oxide coating, the photolytic activity is greater than 5.times.10.sup.-3 cm.sup.-1 min.sup.-1, and coating side visible light reflection is 35% or lower.
RELATED APPLICATION
This application is a divisional application of pending application Ser. No. 09/587,970 filed Jun. 6, 2000, which is hereby incorporated by reference in its entirety.
Supported photooxidation catalysts containing a metal oxide or metal ion as catalyst which is fixed to the support by means of carboxylate moieties are an alternative to existing such catalysts, particularly if low cost supports such as organic polymers, particularly polyethylene, are used. The supported photocatalysts can be used in mineralisation of organic pollutants in both liquids and gases and show reduced leaching of the catalyst and good resistance towards reactive oxygen species generated during the degradation process.
