Platinum, rhodium, palladium, and other precious metals do the dirty work in catalytic converters around the world to keep the air breathable. Those metals usually are washcoated on a ceramic substrate. In conventional catalytic converters, precious metals are wasted due to an unbalanced flow of exhaust gases. Toyota has developed a new type of ceramic substrate called FLAD that solves this problem, the company said.

The new substrate is out of the lab, and is being mass-produced. Initially, the precious-metal-saving catalytic converter will be used in Toyota’s hybrid Lexus LC 500h later this year.
