Frequently Asked Questions

Why is platinum used as a catalyst?

Platinum surfaces can accelerate many useful chemical and electrochemical reactions while remaining sufficiently stable in demanding environments.

Is platinum consumed during catalysis?

A catalyst is not consumed stoichiometrically like a reactant, but real catalysts can lose activity through poisoning, fouling, sintering, dissolution or physical loss.

Where are platinum catalysts used?

Important applications include emissions control, chemical and petroleum processing, PEM fuel cells and selected hydrogen technologies.

Can spent platinum catalyst be recycled?

Yes. Spent catalysts can remain valuable secondary PGM resources even when they no longer meet process-performance requirements.

Does this site provide catalyst synthesis or chemical reaction instructions?

No. Catalyst preparation, reaction recipes, regeneration conditions and precious-metal extraction procedures are intentionally excluded.
