It seems like you're asking about the catalyst used in catalytic converters. Catalytic converters are devices used in vehicles to reduce harmful emissions. They contain a core of ceramic honeycomb coated with catalysts that promote chemical reactions.

The catalysts used in catalytic converters are typically precious metals. These include:

1. Platinum (Pt)
2. Palladium (Pd)
3. Rhodium (Rh)

Sometimes, other metals like nickel (Ni) and iron (Fe) can be used, but they are not as common. The metals are used in a finely divided form to increase their surface area and maximize their effectiveness.

So, to answer your question, the catalyst used in catalytic converters is typically a combination of finely divided platinum, palladium, and rhodium.
