Abstract
Techniques for coating a fiber with metal oxide include forming silica in the fiber to fix the metal oxide to the fiber. The coated fiber can be used to facilitate photocatalysis.
Claims27
A method comprising:
- providing a solution containing at least one metal oxide precursor to a carbon fiber;
- drying the carbon fiber to fix the metal oxide precursor on a surface of the carbon fiber;
- providing a polycarbosilane melt to the carbon fiber;
- and
- heating the carbon fiber to obtain a fiber comprising silica and metal oxide, wherein the fiber comprises a silica phase formed in a core of the fiber, and a metal oxide phase formed on the surface of the fiber.
