How does a platinum-rhodium catalyst work?
Platinum and rhodium are commonly used jointly in catalytic converters. A platinum-rhodium catalyst is a reduction catalyst, which is the first stage of the catalytic converter. It uses platinum and rhodium to help reduce the nitrogen oxides (NO and NO2, together called NOx) emissions. When an NO or NO2 molecule contacts the catalyst, the catalyst rips the nitrogen atom out of the molecule and holds on to it, freeing the oxygen in the form of O2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2. The nitrogen atoms bond with other nitrogen atoms that are also stuck to the catalyst, forming N2. For example: 2NO => N2 + O2 or 2NO2 => N2 + 2O2
The poison for platinum catalyst is?
sulfur
What is a catalyst element?
Platinum, Palladium, Rhodium, etc.
How is a catalyst like platinum different from an enzyme?
Catalysts are compounds that change the speed of chemical reactions. An enzyme is a protein and also a catalyst. So an enzyme can be a catalyst, but a catalyst can't be an enzyme.
Why a catalyst is not considered a reactant or product in a chemical reaction?
If a substance is a reactant or product of a chemical reaction then, by definition, it cannot be a catalyst.
What is the name of the catalyst found in a catalytic converter?
Platinum, palladium and rhodium are metals used as catalyst in converters.
How can you separate platinum out of a catalytic converter?
There are special facilities for catalyst recycling. The effort of getting platinum out of a catalyst isn't worth it due to the low quantity and hazardous for health due to the high toxicity of platinum under the conditions that the catalyst has undergone.
What transition metal is in the catalytic converter?
Platinum is used as the catalyst in a catalytic converter, because this is a precious metal they can be very expensive.
What is a cat converter?
Catalytic converter. A device that use platinum as a catalyst to reduce unburned hydrocarbon emissions from your vehicles exhaust.
What does the catalytic converter do in a car?
The catalytic converter converts toxic gases to harmless gases via a platinum-iridium catalyst. As the hydrocarbons and carbon monoxide pass through this catalyst, the gases are oxidized. This causes them to break down into less toxic elements.
What is a catalyst in catalytic converter?
There are many different catalysts found in cars and trucks, depending on the vehicle and the country it was manufactured for. The most common catalyst is platinum, along with the other platinum-group metals palladium and rhodium. Other metals are also commonly used.

What is the classification of platinum?
Well Platinum is an element so there is really only one type. However, platinum may be used as "sheet" or finely powdered if it was going to be used as a catalyst. Alternatively, it may be used to "plate" a less expensive metal to also act as a catalyst for example in a catalytic converter.

What does Pt over an arrow stand for in chemical equations?
Platinum, Pt, is a catalyst used to promote the reaction. Without the Pt, the reaction is very very slow or does not occur. Platinum is a true catalyst and is not part of the reaction. The catalytic converter in automobiles is an example. The platinum is not consumed, but promotes the breakdown of harmful gases in exhaust to less harmful gasses.
Why a catalyst is not considered a reactant or product in chemical reaction?
A catalyst is unchanged by the reaction, and remains as it was. It causes the start of the reaction, but is still there AFTER the reaction. Example- the catalytic converter on an automobile exhaust contains platinum metal. This causes a chemical reaction to take place in the exhaust gasses, but the metal remains in the converter, and is not consumed.
What is inside a catalytic converter?
A catalyst
