Abstract
A photocatalytic cleaner for air or water includes a photocatalytic material coating a substrate. An anode, positioned a predetermined distance from the substrate, includes a phosphor that emits ultraviolet light in response to bombardment by electrons from a field emission cathode emitting electrons in response to an electric field. The field emission cathode may be a carbon based field emitter material including incorporating carbon nanotubes.
