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.
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
How is a catalyst like platinum different from an enzyme?
A catalyst like platinum is a non-biological substance that speeds up chemical reactions by providing an alternative pathway with lower activation energy. Enzymes, on the other hand, are biological catalysts that are specific to certain reactions and are essential for biological processes. Enzymes are made up of proteins and can be regulated by the cells that produce them, while catalysts like platinum are typically inorganic and do not have this level of specificity or regulation.
Is platinum is a precious stone?
Platinum is a metal. It is found in its metallic form. Its color makes it valuable as jewelry. Its chemical properties make it valuable as a catalyst.
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.
What are examples of anti-catalyst substances?
Examples of anti-catalyst substances include inhibitors and poisons that can interfere with or inhibit the catalytic activity of a catalyst. These substances can bind to the active sites of the catalyst or react with the reactants to slow down or prevent the catalytic reaction from occurring.
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 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 catalyst used in the Ostwald process?

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.

What acts as a catalyst in catalytic converters?
Usually platinum, rhodium and/or palladium.
Where can you find platinum in waste?
by waste i asume you mean trash or junk. cadalytic converters have platinum in them, because platinum is a catalyst. cadalytic converters are found on cars.
