Summary
Automobile catalytic converters reduce air pollution. They convert exhaust gases such as carbon monoxide, nitrogen oxides and unburned fuel into carbon dioxide and nitrogen. This conversion uses three-way catalysts (TWCs). TWCs contain precious metals such as platinum, palladium, and rhodium on a heat-resistant material. The global supply of precious metals is limited and demand continues to rise. One way to reduce the amount of precious metal is to spread it out as single atoms or tiny clusters. This also helps increase efficiency because more metal contacts exhaust gases. The project wil
