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 are the type of catalyst?
Iron is one example of a catalyst, used in ammonia synthesis. Nitrogen oxide and platinum are another example, used in sulfuric acid manufacturing.
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 is catalyst example?
Catalysts are used often in day-to-day life. For example, the catalytic converter in your car which is coated in platinum to reduce carbon monoxide emissions. Also, catalysts are used in industry to speed up the rate of reaction. They offer an optional pathway for the particles and reduces the required activation energy needed for the reaction to occur. Catalysts are widely used in the pharmaceuticals industry and save money in the manufacture of drugs and medicines.
What catalyst is used to oxidize ammonia?
Platinum
What is the name of the catalyst found in a catalytic converter?
Platinum, palladium and rhodium are metals used as catalyst in converters.
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 chemical equation sulfur trioxide when platinum is used as catalyst?
So²+o²=so³
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.
What are the type of catalyst?
Iron is one example of a catalyst, used in ammonia synthesis. Nitrogen oxide and platinum are another example, used in sulfuric acid manufacturing.
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.

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.
Are catalytic converters radioactive?
NO! Catalytic converters contain platinum which is used as a catalyst in many different chemical reactions.
What is the chemical formula hydrogen catalyst?
The chemical formula for a hydrogen catalyst would depend on the specific catalyst being used. Common hydrogen catalysts include platinum (Pt), palladium (Pd), and nickel (Ni).
