Which outcome occurs when a catalytic converter’s platinum nanoparticles sinter?

💡 Explanation

Increased carbon monoxide bypass happens because sintering reduces the catalyst’s surface area, decreasing active sites for oxidation through decreased catalytic activity. Therefore, carbon monoxide conversion efficiency plunges, rather than increasing other process efficiencies under operational constraints or new composition types.
