New composite reduces rare earth element usage in three-way catalytic converters

Green Car Congress

The high-performance, three-way catalytic (TWC) converter is one of the workhorses of emissions reduction for gasoline engines. If the A/F value is suboptimal, the conversion of noxious pollutants (NO x , CO and hydrocarbons) over the precious metal catalysts (Pt, Rh and/or Pd) is incomplete. —Machida et al.
