FIBER GLASS CARRIER HAVING INCREASED SURFACE AREA AND PHOTO-ACTIVE MATRICES FORMED THEREFROM

摘要

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 conventiona l fiber glass processing techniques, such as air-laid mat processes and wet-la id mat processes, and then further treated to provide increased surface area fo r .beta. the deposition of the photo-active material thereon. Treatments to increase the surface area of the fiber glass carrier include etching with ac id solution and coating of the fibers with a high surface area silica. Additionally, methods of distributing the photo-active material in carrier during the formation of the carrier are disclosed.
