Question

Name two metals used in the catalytic converter. How do they help in keeping the environment clean?

Answer 1

Hint: The catalytic converter is an anti-pollution device which is used to convert the chemical pollutant in the exhaust gases. It is found in the many vehicles which are located close to the engine.

Complete answer:
A catalytic converter is a device that is used in the reduction of the toxic gases and pollutants of gases that are exhausting from the internal combustion engine. It is an exhaust emission control device. The catalytic converter is generally used with the internal combustion engines which are powered by the gasoline or diesel. The metals that are used in the catalytic converter are the platinum, palladium and rhodium. Platinum functions both as reduction catalysts and the oxidation catalysts. Platinum is an expensive metal and cannot be used in all applications. So, the two metals that are used in the catalytic converter are the platinum and the palladium.
The catalytic converters are used to clean the environment by depleting the emission of various poisonous gases. The catalysts of the catalytic converter transform the unburnt hydrocarbons into water and carbon dioxide and carbon monoxide is changed to carbon dioxide and nitric oxide is converted to nitrogen gas. The catalytic converters are essential and the initial step to reduce the combustion of harmful and poisonous gases on the road.

Note: The catalytic converter was first established in the American car's production in about 1975. The first catalytic converter was invented by Rodney Bagley.
