Gasoline is refined petroleum used in engines as a fuel. It contains octane that can be converted to isooctane by adding catalysts like platinum and palladium.
<h3>What are catalysts?</h3>
Catalysts are substances that raise the reaction rate by decreasing the activation energy but do not get consumed themselves in a reaction.
Platinum and palladium metals can be used as a catalyst to convert the octane of the gasoline into isooctane as they are oxidation catalyst that converts the fuel components into water and carbon dioxide.
Therefore, platinum and palladium are used as catalysts in converting octane.
