Metal catalytic converters are an essential component of modern vehicles. They play a crucial role in reducing harmful pollutant emissions, thus significantly contributing to environmental protection. In this article, you will learn everything you need to know about metal catalytic converters, from how they work to potential problems and solutions.
What is a Metal Catalytic Converter?
A metal catalytic converter, also known simply as a catalytic converter or “cat,” is a component in a vehicle’s exhaust system. Its purpose is to convert harmful exhaust gases into less harmful substances before they are released into the environment. The process is based on chemical reactions accelerated by the catalytically active metals within the converter, typically platinum, palladium, and rhodium. These metals are applied to a honeycomb structure to increase the surface area and enhance the conversion efficiency.
The metal catalytic converter primarily reduces emissions of carbon monoxide (CO), unburned hydrocarbons (HC), and nitrogen oxides (NOx).

Dr. Klaus Müller, a renowned expert in exhaust technology, emphasizes in his book “The Chemistry of Exhaust Purification”: “The metal catalytic converter is one of the most important inventions in automotive environmental protection. Without it, pollutant emissions from our vehicles would be many times higher.”
How Metal Catalytic Converters Work and Their Importance
The function of the metal catalytic converter is based on the catalytic oxidation and reduction of pollutants in the exhaust gas. Carbon monoxide (CO) is oxidized into carbon dioxide (CO2), unburned hydrocarbons (HC) are burned into carbon dioxide (CO2) and water (H2O), and nitrogen oxides (NOx) are reduced into nitrogen (N2) and oxygen (O2). These reactions occur at high temperatures generated by the engine’s combustion.
The importance of the metal catalytic converter for environmental protection is immense. By reducing pollutant emissions, it contributes to improving air quality and decreasing health risks from exhaust fumes. A functioning metal catalytic converter is therefore essential for every modern vehicle.
Problems and Solutions for Metal Catalytic Converters
A common defect in metal catalytic converters is clogging due to residues from the combustion process. This can lead to performance loss and increased fuel consumption. Damage to the honeycomb structure from mechanical impact or overheating can also impair the converter’s function. In such cases, replacing the catalytic converter is usually necessary.
Sometimes, the converter can also be damaged by faulty spark plugs or a defective oxygen sensor (Lambdasonde). Therefore, it is important to regularly inspect these components and replace them if necessary.
