What is a catalytic converter, and what makes them so valuable?

  Starting in the mid-70s, various governments wanted to reduce harmful emissions and lower the air pollution coming from our car. After about 20 years, the catalytic converter became essential for every vehicle exhaust system. The catalytic converter takes toxic gases and transforms them into a less harmful form.  Poisonous or harmful gasses such as carbon monoxide, sulfur oxide, and nitrogen oxide release into the atmosphere during the combustion process. The catalytic converter is a metal box located underneath your vehicle, usually attached to the exhaust pipe. The part gets its namesake from the scientific reaction taking place inside. A catalyst is any substance that causes a chemical reaction without being affected. Noble metals inside the converter, such as platinum, rhodium, and palladium, act as the catalyst in this case. These metals accelerate the chemical reactions, so it's much safer for the environment by the time it hits the air.  Several chemical ... read more
