used auto catalytic converterplatinum content in catalytic convertersmethods of platinum recoveryAt present, every launched car must be equipped with a catalytic converter, in which the precious metals such as platinum, palladium and rhodium play catalytic role. Catalytic converters have a limited life ...
Fig. 3. Structure of a catalytic converter. Reprinted from Ref. [9]. Copyright ETH Zurich library (open access). Platinum could be considered as the lone royal member that has witnessed all the advancements in the catalysis field. More experimental observations on heterogeneous catalytic oxidation...
Automotive catalytic converters (ACCs) play an essential role in exhaust systems to reduce the emission of harmful pollutants, such as carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx). A typical converter is ceramic-based and consists of a substrate made of cordierite (2MgO...
Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. Platinum is used in the glass industry[7] to manipulate molten glass which does not "wet" platinum. As a heavy metal, it leads to ...
acatalytic converter, which allows the complete combustion of low concentrations of unburned hydrocarbon from the exhaust into carbon dioxide and water vapor. Platinum is also used in the petroleum industry as a catalyst in a number of separate processes, but especially in catalytic reforming of ...
As a catalytic converter undergoes aging, sulfur compounds present in diesel fuel can accumulate on its surface, leading to a decline in its catalytic performance [117]. Additionally, elevated operating temperatures can contribute to the clustering of platinum nanoparticles, resulting in a reduction of...
Platinum and its alloys are used in surgical tools, laboratory utensils, electrical resistance wires, and electrical contact points. It is used in the catalytic converter, an optional component of the gasoline-fuelled automobile exhaust system. It is also used in the chemical, electrical, glass ...
For example, the catalytic converter in an automobile's exhaust system may contain a platinum metal. Discovery and naming The first known reference to platinum can be found in the writings of Italian physician, scholar, and poet Julius Caesar Scaliger (1484-1558). Scaliger apparently saw ...

For several decades now all petrol-driven motor vehicles have had to feature a catalytic converter in their exhaust systems to meet the requirements of emissions legislation. These feature a high surface area coated with platinum, palladium, and rhodium, which catalyses the high-temperature breakdown...
