What Metal Elements Are In A Catalytic Converter

Due to their ability to accelerate chemical reactions while maintaining their chemical stability, rare earth metals are frequently utilized as catalysts. Platinum, palladium, and rhodium are now the essential items that are employed in emissions control, one of the most frequent.

  • Platinum is now the most efficient catalyst to decrease pollutants from diesel and gasoline. The priciest catalyst material is platinum. As a result, luxury automobiles, as well as other expensive vehicles, like to use it as their preferred metal.
  • Palladium is a preferred metal for usage in mass-produced automobiles since it is less costly than platinum. But compared to other catalytic materials, palladium remains more costly.
  • Because it possesses the best resilience to toxicity despite being the weakest active of such three metals, rhodium is advantageous for some drive applications. It is suitable for some engine applications since it has the best toxin resistance.

Let’s get started with the article’s primary topic right away.


Rhodium is present at minute levels in catalytic converters, which are crucial for lowering vehicle emissions. Rare earth metal rhodium is frequently employed in catalytic converters. Rhodium would be a pricey metal that may fetch high prices on the scrap market.

How Does Rhodium Appear?

Fine steel with a silvery white tint, rhodium is a component of a platinum group and is incredibly reflective, resistant to corrosion, challenging, and noble. The primary usage of rhodium serves as a mixture to make platinum more durable.

Due to its high level of reflection, it provides jewelry with a lovely finish and creates highly reflecting surfaces in optical equipment. Rhodium is costly since it is scarce and difficult to get.

Why Does A Catalytic Converter Contain Rhodium?

Rhodium is a metal used in catalytic converters to lessen the amount of nitrous oxide pollution discharged into the air by exhausts from moving vehicles. This aids in reducing air pollution, primarily due to combustion engine usage.

Among the crucial components in a catalytic converter is rhodium, which cleans the pollutants first before gasses are discharged into the atmosphere in conjunction with some other elements like palladium.

With the help of palladium and platinum, metallic rhodium inside catalytic converters combines with other elements to transform dangerous particles of emissions into something less harmful. Thus, the atmospheric tolerance level serves as the objective for neutralization.

What Are The Uses Of Rhodium ?

Because of its extraordinary strength, rhodium is used in the chemical process industries as a catalyst for producing acetic, nitric, and hydrogenation processes. It also finds application inside the catalytic converter because it is corrosion-resistant and ultra-shiny, making it beneficial in various sectors.

Since metals are a crucial element of the converter, they are the primary factor inside the cat’s ability to reduce emissions concerns rather than addressing them alone successfully. Because of their numerous applications in industry and commerce, precious metals continue to have additional economic worth in addition to their initial usage.

How Much Rhodium Is In A Catalytic Converter?

Rhodium is often included in catalytic converters in amounts ranging from 1 to 2 grams, although they typically weigh 1.2 kg (2.2 pounds).

One standard catalytic converter typically comprises one to two grams of rhodium, two to seven grams of palladium, and between three and seven grams of platinum. However, the amounts differ by type. When countless amounts of junk catalytic converters are salvaged, that results in significant gains.

How Much Is Rhodium Worth?

Rhodium is a rare metal used in catalytic converters, which has caused its price to rise significantly in recent years. While the price of rhodium has mostly been consistent over the past ten years, these have climbed dramatically over the past two years. Rhodium currently costs roughly $287 per gram.

In 2022, rhodium will cost $461.36 per gram, around $14,350.00 for every ounce. It is, therefore, among the most expensive precious metals. Its rarity and distinctive qualities account for the premium price. High melting point and strong corrosion resistance are two qualities of rhodium. Because of the exceedingly low supply, future price increases are almost certainly in store.

Does Old Catalytic Converter Rhodium Retain Its Characteristics Over Time?

Rhodium is inside the honeycomb part of the converter and is easily recoverable via recycling. Rhodium used in catalytic converters maintains its properties and may be regenerated without concern about deterioration.

Acids, water, and oxygen are the lowest likely to impact rhodium. As a result, neither the acidic poisons nor the fumes will cause the metal to degrade. During catalytic carboxylation, which refers to the creation of carbonyls, the material generates acetic acid. As a result, it is a reliable metal that seldom loses its qualities.

The recycling business should have state-of-the-art machinery and use energy-efficient procedures. An efficient waste disposal infrastructure is also required to lessen environmental contamination at the expense of metal.

Which Automobile Models Have Catalytic Converters Made Of The Most Valuable Metals?

Based on the type and brand of the automobile, a converter’s raw material content might change.

Statistical information from 2020 indicates that the Ferrari F430’s $3,770.00 exhaust system was the priciest one available. In addition, the F430 required two of these, costing $7,540 before work for a complete replacement.

An exhaust system for the Mercedes-Benz S600 costs approximately $400 and is made of palladium. Platinum valued at $700 is used in the converters along the Audi A8 L W12 Quattro. Rhodium valued at $1300 is found in the converters of such BMW 760iLi.


How much rhodium is in a catalytic converter? Rhodium typically weighs between 1 and 2 grams in emissions controls. Even though one gram may seem negligible, pure rhodium costs $290 per gram.
