Claims24
A photocatalytic surface system that incorporates a UV-A or visible light activated titania-based photocatalytic material in contact with a matrix, where the photocatalytic material is designed to reduce oxidation of the matrix.
A method of manufacturing a photocatalytic surface system, the method comprising;
- forming a titania-based photocatalytic material designed to reduce oxidation in a matrix, mixing the photocatalytic material into a paste or liquid thereby dispersing the photocatalytic material in the paste or liquid, dispensing the paste or liquid in a controlled pattern, hardening the paste or liquid to form a solid matrix having a defined shape based on the controlled pattern, thereby suspending the photocatalytic material in the matrix, exposing at least a portion of the photocatalytic material at a surface of the matrix thereby forming a photocatalytic surface system, and exposing the photocatalytic surface system to UV-A or visible light, thereby stimulating photocatalytic activity.
A liquid cleaning agent for cleaning a solid surface, that provides photocatalytic enhancing species to the surface.
