The All-Around Benefits of Ruthenium: From Automotive to Biomedicine
Ruthenium is a chemical element with the symbol Ru and atomic number 44. It is a rare, silvery-white metal that is part of the platinum group of elements and is considered one of the least abundant elements in the Earth's crust. Despite its rarity, ruthenium has a wide range of
applications in various industries due to its unique properties and characteristics.
According to the US Geological Survey, the world's reserves of ruthenium are estimated to be around 1,000 tons. These reserves are mainly located in Russia, South Africa, and North America. The largest producer of ruthenium is Russia, followed by South Africa and Canada. Ruthenium is typically obtained as a byproduct of the mining and refining of platinum and nickel ores, and it is estimated that only around 1-2% of ruthenium is produced annually. This, combined with its many useful applications, means that ruthenium can command high prices on the market. Despite its rarity, ruthenium is widely used in various industries, and its demand is expected to continue to increase as new applications for the metal are developed. To meet this growing demand, mining companies are investing in exploration and production efforts to locate and extract new ruthenium reserves.
Catalytic Converters and Environmental Sustainability

- Catalytic converters are an essential component in modern automobiles, as they help to reduce harmful emissions produced by the internal combustion engine. A catalytic converter contains a ceramic or metallic substrate coated with a mixture of precious metals, including platinum, palladium, and ruthenium. These metals act as catalysts, promoting chemical reactions that convert the toxic pollutants in the engine's exhaust gases into less harmful substances.
- Catalytic converters work by using the precious metals to catalyze a chemical reaction between the toxic pollutants in the exhaust gases and the oxygen in the air. This reaction transforms carbon monoxide, hydrocarbons, and nitrogen oxides into carbon dioxide, water vapor, and nitrogen gas, respectively.
- Ruthenium is a valuable component in catalytic converters due to its high temperature stability and resistance to poisoning, or the inability of a catalyst to function properly due to the presence of certain substances in the exhaust gases. This makes ruthenium an ideal choice for use in catalytic converters for diesel engines, as diesel exhaust can be more challenging to treat than gasoline exhaust.
- In addition to reducing harmful emissions, catalytic converters can also improve fuel efficiency and engine performance. This makes them an important component in reducing the environmental impact of transportation, and they are required by law in many countries to be installed on all new vehicles.
- In conclusion, catalytic converters are an essential component in modern automobiles, as they help to reduce harmful emissions and improve fuel efficiency and engine performance. Ruthenium, along with other precious metals, plays a key role in the functioning of catalytic converters, and its use in this application will likely continue to be important in the future.
