Which mechanism causes decreased yield when catalytic converters experience overheating?

💡 Explanation

Sintering occurs because high temperatures cause the catalyst material to coalesce, decreasing the active catalytical surface area; therefore catalytic activity declines, rather than backpressure increases, influencing thermal expansion, or poisoning which typically deals with substances binding catalyst material.
