The photocatalytic applications of titanium dioxide are widely reported and include water purification, air purification and self-cleaning, however, due to the large band gap (ca. 3.2 eV) of titania, coatings have a limited efficiency. To therefore take full advantage of this material, low cost deposition processes are required. Titania is often incorporated into paints and concrete building materials to passively act, purifying contacting air, and removing harmful NOx and VOCs (volatile organic compounds). Incorporating titania in this manner takes advantage of the large exposed area of a building surface while minimising the cost relative to deposition processes such as PVD. Herein, we report a novel deposition technique LPC (low pressure coating) for the inclusion of photoactive titania in ductile surfaces. LPC is a low cost, easily scalable technology with potential application in the production of air purifying building materials. |
