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.
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
What is catalyst usually used for 2co 2no n2 2co2?
Usually, Platinum or Rhodium attached to a ceramic surface is used as a catalyst in this reaction.
What catalyst used in the Ostwald process?
It help speed up the process
What are examples of anti-catalyst substances?
they are inhibitors of chemical reactions or diminishes the activity of a catalyst. The inhibition is temporary when the poison is adsorbed on the surface of the catalyst in preference to the reactants. The Permanent poisoning is when a covalent bond is formed between the poison and the catalyst.for example volatile sulfur and volatile silicon cause permanent poisoning during many cases. Arsenic are poison to platinum. In the reaction of decomposition of H2O2 by platinum, HCN act as poison. In another case CO act as poison to copper during the reaction of hydrogen and ethylene.
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 catalyst is used to oxidize ammonia?
Platinum
What is a catalyst element?
Platinum, Palladium, Rhodium, etc.
Why are catalysts usually expensive?
Because some of the catalyst is rare such as platinum that is use as catalyst to produce ammonia.
What is the name of the catalyst found in a catalytic converter?
Platinum, palladium and rhodium are metals used as catalyst in converters.
What chemical element is a good catalyst?
An important example is platinum.
What makes catalytic converters so valueble?
The platinum catalyst.
What is the chemical symbol for platinum oxide?
Platinum dioxide, also known as Adams' catalyst, is usually represented as platinum(IV) oxide hydrate, PtO2-H2O. It is a catalyst for hydrogenation and hydrogenolysis in organic synthesis. This dark brown powder is commercially available. The oxide itself is not an active catalyst, but it becomes active after exposure to hydrogen whereupon it converts to platinum black, which is responsible for reactions.
What is a catalyst in catalyst converters?
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.

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.
