Why is platinum used in some chemical catalysts?
ChemistryCatalysis
Quick Answer
Platinum is a good catalyst because it speeds up reactions without being consumed. Its surface helps reactant molecules adsorb and react more easily.
The Full Story
A catalyst lowers the activation energy needed for a chemical reaction, making the reaction happen faster. Platinum is especially useful because its surface interacts well with many reactants while remaining chemically stable. This makes it valuable in car catalytic converters, industrial chemistry, and some laboratory processes. Other precious metals, such as palladium and rhodium, are also important catalysts for similar reasons.
