A fiber glass carrier having a high surface area is disclosed for use as a carrier for photo-active materials, such as photocatalyst materials and photovoltaic materials. The fiber glass carrier can be formed by conventional fiber glass processing techniques, such as air-laid mat processes and wet-laid mat processes, and then further treated to provide increased surface area for .beta. the deposition of the photo-active material thereon.

Why it's free to use
- Filed June 14, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 14, 2020.
