what metals are in a catalytic converter

The catalyst component of a catalytic converter usually contains three precious metals, which are platinum (Pt), palladium (Pd), and rhodium (Rh) . These metals are extremely rare and have a broad range of applications in addition to catalytic converters. Platinum, for example, is used in laboratory and dental equipment, electrical contacts and electrodes, and jewelry, while palladium plays a key role in fuel cell technology. The value of these metals in the PGM market is even higher than that of gold. The reason why catalytic converters are often stolen is that they contain a considerable amount of these valuable metals, which can cost up to $20,000 per ounce if sold.
