Ceramics that breathe oxygen at lower temperatures help us breathe cleaner air

With the shift to electric cars a cumbersome process, improvements to exhaust gas purification in petrol or diesel cars are crucial in the fight to reduce emissions. A research group has developed a Cerium-Zirconium-based oxide that boosts the purifying qualities of ceramics inside catalytic converters — a device attached to conventional cars that converts harmful gases to less-toxic pollutants.
