In December 2019, rhodium cost $6,000 per ounce and by March 2021, the price rose to $21,000 per ounce, with platinum and palladium seeing similar rises. [ 14 ] The brothers incorporated the business as DG Auto Parts in February 2020 and moved to the Freehold, New Jersey, site.
Catalytic converter prototypes were first designed in France at the end of the 19th century, when only a few thousand "oil cars" were on the roads; these prototypes had inert clay-based materials coated with platinum, rhodium, and palladium and sealed into a double metallic cylinder. [6]

Catalytic-converter-equipped vehicles have helped cut other air pollutants by more than 3 billion tons worldwide between 1975 and 2000; of this 1.5 billion short tons was in the United States. Automobiles meet emission standards that required reductions of up to 98+ percent for HC, 96 percent for CO, and 95 percent for NOx compared to the ...
The introduction of the three-way catalytic converter by Volvo in 1976 increased the demand for rhodium. The previous catalytic converters used platinum or palladium, while the three-way catalytic converter used rhodium to reduce the amount of NO x in the exhaust. [22] [23] [24]
High surface area facilitates catalytic reaction or filtration. The open spaces in the cross-sectional area are 72 to 87% of the frontal area, so resistance to the flow of gases through the holes is low, which minimizes energy consumed forcing gases through the structure. The monolith is a substrate that supports a catalyst.
Stillwater Mining Company is engaged in the development, extraction, processing, refining and marketing of palladium, platinum and associated metals (platinum group metals or PGMs) from a geological formation in the Stillwater igneous complex in south central Montana known as the J-M Reef and from the recycling of spent catalytic converters.
As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Carbon in the form of diamond can be more expensive than rhodium. Per-kilogram prices of some synthetic radioisotopes range to trillions of dollars.
