Conventional Three-way catalysts consist of precious metals and metal oxide supports. The sintering of precious metals is known to cause a decrease in the catalytic activity. Recently, we discovered that Pt/Ce-based oxide catalysts have high durability compared to Pt/Al2O3 following aging treatment. Using X-ray absorption analysis, we found that the Pt-O-Ce bond, that is, the Pt-support interaction, inhibits the sintering of Pt particles.
