Pt has been economically favored over Rh and Pd. However, Pt-based three-way catalysts
(TWCs) have been studied less than Pd-and Rh-based TWCs; therefore, their properties …

In three-way catalytic converters, momentary perturbations of the exhaust gas composition
between fuel-rich (reducing) and fuel-lean (oxidizing) conditions near the stoichiometric …

The cost of Pt is currently lower than that of Pd and Rh, however, Pt-based three-way
catalysts (TWCs) have attracted less attention than Pd-and Rh-based TWCs. Consequently …

The next-generation Euro 7 standard proposed much lower pollutant limits from gasoline
vehicles, specifically for CO and NO x, which would be challenging for the three-way …

Self-regenerative materials are keys to the development of stable catalysts used under high
temperature condition, eg, three-way catalyst converters in automobiles. Among others …

Acid Orange 7 (AO7) is one of the most common azo dyes; however, its strong azo bond
makes them difficult to biologically degrade. We sought to degrade AO7 dye using CeO2 as …

The Pd distribution and the CeO2–Al2O3 combination are among the decisive factors for the
performance of commercial three-way catalysts. Generally, the sufficient doping of Pd into …

This study demonstrates the reaction behavior during the purification of model automotive
exhaust gases over Pd catalysts before and after thermal degradation. In particular, to …

The effect of Pd loading on the redox characteristics of a ceria support was examined using
in situ Pd K-edge XAS, Ce L3-edge XAS and in situ X-ray diffraction techniques. Analysis of …

The three-way catalysts (TWC) are required to have high thermal stability and excellent
catalytic activity. The MgAl2O4 spinel is a thermal stable material, but its reactivity is …
