- Abstract
A diesel particulate filter (DPF) substrate was fabricated from alkali-resistant α-AlO to make a practical use of alkali metal catalysts for diesel soot oxidation. The fundamental properties of the α-AlO-DPF, including its particle filtration efficiency, pressure drop, and thermal durability were comparable to those of the conventional DPFs. The diesel soot oxidation activity of the catalyzed α-AlO-DPF with a washcoat of alkali metal-based catalyst was, even after thermal aging, much higher than that of the conventional catalyzed-DPF with platinum group metal catalysts.
