Systems and methods for treating automotive vehicle emissions on board an automotive vehicle include the use of waste heat recovery, electrochemical water splitting, phototcatalytic water splitting, and selective catalytic reduction. Waste heat recovery is used to power electrochemical water splitting, or photocatalytic water splitting. Photons collected from a solar panel are used in photocatalytic water splitting, or in photo-assisted selective catalytic reduction. Hydrogen gas generated by water splitting is used in conjunction with catalytic reduction units to catalytically reduce NOx in an engine exhaust gas.

Thermal- and photo-assisted aftertreatment of nitrogen oxides

Exhaust gas is treated onboard a vehicle. Solar energy is converted into electricity, which is used to power an electrochemical cell mounted onboard the vehicle. Oxygen and hydrogen are produced by the electrochemical cell. Heat and the oxygen produced by the electrochemical cell are provided to a particulate matter filter onboard the vehicle, thereby oxidizing particulate matter disposed on the particulate matter filter.
