An aspect of the present disclosure is directed to a system for removing particulate matter from an exhaust stream. The system may include an ionization device configured to ionize particles of an exhaust stream. The system may further include an electromagnetic field generating device configured to deflect the ionized particles onto an inner-surface of an exhaust passageway, the inner-surface of the exhaust passageway being coated with a substance for lowering activation energy for a reaction of the ionized particles. The system may further include a regeneration means configured to remove particles from the exhaust passageway.
