Your car emits pollutants, but the catalytic converters in your car clean them up before they reach the environment. Nevertheless, do you know the ingredients that remove the pollutants from the exhaust?

When combined with other metals like palladium, rhodium helps to remove pollutants from exhaust fumes before they are released into the environment.

Rhodium is a precious metal that is more expensive than gold since it is so scarce. Catalytic converters contain varying amounts of rhodium. Learn more about the rhodium used in catalytic converters by continuing to read this article!

So, How Much Rhodium Is in Catalytic Converter?

The manufacturer and type of the vehicle, as well as the powertrain, all have a role in determining the answer to this question. The same engine could be used in multiple nations with different converters.

Rhodium content in catalytic converters ranges from 1 to 2 grams on average, with a total weight of 1 to 2 kilograms (2.2 pounds).

A gram of Rhodium can cost up to $290, however you can easily get this by recycling your old converter.

Can Rhodium Coming From A Used Catalytic Converter Lose Its Properties?

The honeycomb portion of the converter contains rhodium, which may be easily recovered through recycling. Catalytic converter rhodium retains its qualities and can be recycled without fear of degradation.

Rhodium is one of the few metals that can withstand exposure to the elements. Thus, the acidic poisons created by the exhaust fumes will not harm the metal.

The metal catalyzes carboxylation, which is the synthesis of carbonyl molecules, to generate acetic acid. Because of this, it is a durable metal that rarely loses its usefulness.

The recycling organization should be equipped with cutting-edge equipment and employ energy-saving practices. An effective waste management system is also needed to reduce environmental pollution at the cost of metal.

What Cars Have Very Expensive Catalytic Converters?

Due to the fact that Ferrari F430 has two catalytic converters, it is the most expensive. Lamborghini, Ford Mustang, Ram 2500, and Ford F 250 all feature catalytic converters that aren’t cheap.

Because of the larger engines in these vehicles, more or larger catalytic converters are required. A automobile would therefore need to use more rhodium metal if it needed two converters. More rhodium would be required to adequately clean fumes from larger catalytic converters as well.

Where Does Rhodium Come From?

William Wollaston discovered the non-reactive metal rhodium in 1803 and it is a byproduct of nickel and copper refinement.

What Kind Of Metal Is Rhodium?

In terms of the periodic chart, rhodium belongs to the platinum metals of periods 5 and 6 and group 8. Most of the time, it’s employed as a hardening alloy for platinum.

Highly shiny and non-reactive, this rare white silver metal resists rust and corrosion. It can be used to make reflective surfaces for optical instruments and to give jewelry an appealing polish.

Platinum, when combined with rhodium, hardens and loses mass more slowly at high temperatures than the metal alone. Fuel cells, catalysts in high-temperature chemical conditions, and even spark plug electrodes might benefit from the alloys. For the production of nitric acid, this alloy is an excellent choice since it is more resistant to acids and high temperatures.

Where Is Rhodium Found?

There are only a few known deposits of this metal, which is the rarest of the platinum group metals.

Why Does Rhodium Become So Expensive?

Rhodium is used to remove exhaust gases from automobiles, which has led to a surge in demand. To fulfill tough pollution regulations, the automotive sector has increased its demand for its products.

Thus, the lack of supply has led to a price increase that has made it more expensive than gold. An ounce of rhodium costs more than a Toyota Innova, a Kia Carnival, or a Tata Harrier. In the United States, rhodium catalytic theft is on the rise because of a shortage of the metal.

Because South Africa was the world’s largest producer of rhodium, the closure of the country’s mines added to the metal’s price. Rhodium’s price has been affected by a lack of supply as a result of declining metal mine production.

As a result, there is a lack of rhodium on the market, which has pushed up the price of the products.

The mining industry has been hit hard by the corona pandemic, which has prompted new investments. Underground mines in South Africa have yet to reach full operational capacity, as the country was the hardest devastated.

More rhodium metal is needed to meet strict emission standards in Europe, China, and the United States. Most automobile manufacturers would utilize the metal to clear exhaust gases since it is highly resistant to corrosion. The high demand for the metal effects the metal price.

In addition, because of its chemical and physical qualities, it is used in other sectors, increasing demand for it.

Rhodium is difficult to remove from its ore, and the metal’s scarcity keeps its price high. Its price is highly volatile, and this may be the norm rather than the exception. As a result of the anticipated price rises, metal supplies may be restricted, resulting in a shortage and further price increases.

What Is The Price Of Rhodium Today?

The price of rhodium depends on the purity of the metal and might be more or less than $290 per gram of pure rhodium. Middlemen can make money by purchasing metal from miners and reselling it to automakers at a profit.

There is a possibility that supply and demand will increase the value of rhodium in the future, making it a profitable investment.

To sell an outdated catalytic converter, you may get anywhere from $399 to $1500 at the wrecking yard. Other precious metals, such as palladium, are to blame for the high pricing. Establish a recycling company to extract the metal from the catalytic converter and resell it at a profit.


Catalytic converters, which remove carbon dioxide and other pollutants from the atmosphere, are required by strict automotive production standards.

However, because of the strong demand for this rare metal, its price has skyrocketed. Pure rhodium currently costs $290 per gram. High demand from automobile manufacturers, drop in mining owing to coronavirus pandemic, and supply chain distortion have all had an impact on the metal’s supply chain.
