The current invention consists of a method and device that is coated with at least one predeposited photocatalyst to reduce or eliminate exhaust emissions and powered by a thermoelectric generator. The method and device comprises a light source emitting sufficient light between 10 nm and 700 nm for the photocatalyst coating and a means to attach said method and device to the source of exhaust emissions.

A catalytic converter includes a hydrocarbon catalyst trap including BEA zeolite configured to adsorb iso-octane at ambient temperatures and desorb iso-octane at temperatures between 150 C. and 170 C., and active metal supercage impregnated USY zeolite configured to adsorb and coke iso-octane at temperatures greater than 150 C.

This disclosure relates generally to an emitter for dissociating exhaust gases on a molecular level into their respective elemental constituents. The emitter includes a palladium plated anode and a cathode, at least a portion of which is palladium plated. When properly powered, the emitters create a non-linear quantum dissonance field to dissociate molecules in exhaust.

An exhaust treatment apparatus (ATA) for reducing one or more components of the airstream directed through the ATA. The ATA includes an airstream inlet, an airstream outlet, and an airstream path directed through the ATA from the airstream inlet to the airstream outlet, and at least one corona/NTP generating region for altering a composition of an airstream. The ATA includes an outer enclosure forming one electrode surface and a second electrode surface positioned within and electrically insulated from the outer enclosure electrode surface, where an area between the outer enclosure electrode surface and the second electrode surface forms at least a part of the airstream path directed through the ATA. The second electrode surface includes a series of ridges directed towards the outer enclosure that encourage corona generation. A method is provided for using the ATA for treating an airstream, including an exhaust airstream from a combustion engine, as well as an exhaust airstream from a compression-ignition (diesel) engine.
