A catalytic converter is an essential component of a vehicle's exhaust system that helps to reduce the emissions of harmful pollutants such as carbon monoxide, nitrogen oxides, and hydrocarbons. It achieves this by using a series of chemical reactions to convert these pollutants into less harmful substances before they are released into the atmosphere.

As the automotive industry continues to evolve, one technology that has been gaining significant attention is the catalytic converter.

In developing countries, where air pollution is a major problem, there are several new trends in catalytic converter technology, Low-cost materials, Nanostructured catalysts, Alternative fuels, Integrated aftertreatment systems, Wireless monitoring
