Catalytic converter prototypes were first designed in France at the end of the 19th century, when only a few thousand "oil cars" were on the roads; these prototypes had inert clay-based materials coated with platinum, rhodium, and palladium and sealed into a double metallic cylinder. [6]
He built a generic catalytic converter capable of reducing carbon monoxide and unburned hydrocarbons from automobile exhausts. For his design, he received U.S. Patent 2,742,437 in 1956. [ 2 ] [ 13 ] [ 32 ] Catalytic converters eventually became standard equipment in American cars, following passage of the Clean Air Act , introduced by Edmund S ...
Carl Donald Keith (May 29, 1920 – November 9, 2008) was a chemist who was inventor of the three-way catalytic converter, which has played a dramatic role in reducing pollution from motor vehicles since their introduction in the mid-1970s.
Adolphe Kégresse (1879–1943), France/Russia – Kégresse track (first half-track and first off-road vehicle with continuous track), dual-clutch transmission Carl D. Keith (1920–2008), together with John J. Mooney (1930–2020), U.S. – three way catalytic converter
Catalytic-converter-equipped vehicles have helped cut other air pollutants by more than 3 billion tons worldwide between 1975 and 2000; of this 1.5 billion short tons was in the United States. Automobiles meet emission standards that required reductions of up to 98+ percent for HC, 96 percent for CO, and 95 percent for NOx compared to the ...

Mooney (right) at the award ceremony for the National Medal of Technology and Innovation for the invention, application and commercialization of the three-way catalytic converter (2003) Mooney was elected a Fellow of Society of Automotive Engineers (SAE) in 1990 for his efforts in exhaust emission control.
In 1970, Taylor joined General Motors where she is known for her work at General Motors on catalytic converters that helped reduce pollution from car exhaust, following work done earlier by Eugene Houdry. [1] Taylor developed catalytic converters that converted nitric oxide into nitrogen, instead of ammonia, a toxin to humans. [1]
