Abstract
Photochemical catalysts and methods for their manufacture and use are provided. In one aspect of the invention, a photochemical catalyst includes an optical microfiber coated with a catalytic amount of a molecular sieve, such as a zeolite. In one preferred form, at least a portion of the outer surface of the optical microfiber is cladding-free to allow radial transmission of light to the molecular sieve coating. In another aspect of the invention, a method of making a photochemical catalyst is provided that includes depositing a catalytic amount of a molecular sieve onto an outer surface of an optical microfiber, wherein the optical microfiber is configured to transmit light to the molecular sieve. A method of photocatalysis utilizing the above-described photocatalysts includes exposing the photocatalyst and a reactant to a light source to photocatalytically react the reactant.
