Found in: Used in catalytic converters (ICE, HEVs, and PHEVs). Palladium and platinum are extracted from ore deposits, often found alongside nickel and copper ores. Both palladium and platinum are crucial components in catalytic converters, which are devices used to reduce harmful emissions in v...
So, why are these converters are so interesting to thieves? Money. Thieves know they can resell these converters for cash. You see the catalytic converter contains 3 different metals. Platinum, Palladium, and Rhodium. The price of these metals hasrisen greatlyover the past few years. These met...
Heat is important for catalytic converter function — reactions start at 800°F (426°C) — so some catalytic converters are built into the exhaust manifold. This helps get them up to operating temperature sooner, reducing or eliminating undesirable emissions. These reactions all happen inside the ...
In addition to catalytic converters, other automotive applications for platinum include oxygen sensors and spark plugs. Palladium is used in virtually all electronics Iridium is used to make high-purity crystals, which have applications in the medical, petroleum, and security industries. ...
One of the main causes of damage to catalytic converters is high temperatures. The usual operating temperature is 150-600°C, but misfiring and high driving speeds can lead to temperatures of up to 1000°C. Unburnt fuel can damage a catalyst because it can cause an exothermic reaction on th...

Excellent corrosion resistance combined with various inherent properties justify the many costly applications of these metals and alloys.Gold circuit in the electronics industry, various dental alloys, and platinum coatings for catalytic converters are a few of the better, known examples. 贵重金属包括金...
A comprehensive and consistent picture of the catalytic cycle of hydrosilylation of alkenes catalysed by hydrido-bridged diplatinum complexes has been derived by means of electronic structure calculations at the B3LYP and CCSD(T) levels of theory, using the LANL2DZ basis set. All crucial reaction...
