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?
The most common poison for a platinum catalyst is carbon monoxide (CO). CO can adsorb onto the surface of the catalyst and block active sites, reducing its effectiveness in catalyzing reactions.
What catalyst is common in automobile exhaust?
The common catalyst in automobile exhaust is a catalytic converter, which contains precious metals like platinum, palladium, and rhodium. This device helps to convert harmful pollutants such as carbon monoxide, nitrogen oxides, and hydrocarbons into less harmful substances like carbon dioxide, nitrogen, and water vapor through a chemical reaction.
What substance acts as the catalyst in a car's catalytic converter?
Metal
What catalyst used in the Ostwald process?
Platinum is the catalyst typically used in the Ostwald process, which is a method for producing nitric acid through the oxidation of ammonia. The platinum catalyst plays a critical role in promoting the conversion of ammonia to nitric oxide, an important intermediate in the process.
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 is a cat converter?
Catalytic converter. A device that use platinum as a catalyst to reduce unburned hydrocarbon emissions from your vehicles exhaust.
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.
Is Platinum in a catalytic converter element or compound?
Platinum in a catalytic converter is an element. It is a noble metal that acts as a catalyst in the converter to facilitate chemical reactions that convert harmful pollutants in exhaust gases into less harmful substances.
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 the catalyst in a 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 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.
What role does platinum play in a catalytic converter?
Platinum in a catalytic converter acts as a catalyst, helping to convert harmful gases like carbon monoxide, nitrogen oxides, and hydrocarbons into less harmful substances like carbon dioxide, nitrogen, and water vapor through chemical reactions.
What is inside a catalytic converter?
A catalyst
