It is a great challenge for vehicles to satisfy the increasingly stringent emission regulations
for pollutants and greenhouse gases. Throughout the history of the development of vehicle …

A highly active catalyst of K-supported Pr 2 Sn 2 O 7 pyrochlore nanosphere (K/PrSn) was
synthesized by impregnation method with K 2 CO 3 as precursors for soot oxidation in this …

Cerium oxide is an interesting semi-conductor that can be easily functionalized by several
fabrication tactics, such as morphological improvement, metal incorporation, or composite …

Reduction–oxidation cycles in oxides are ubiquitous in oxygen storage and transport,
chemical looping processes, and fuel cells. O-atom addition and removal are mediated by …

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 …

A large set of unsupported ceria catalysts has been synthesized, physicochemical and
electrochemically characterized, and tested in a representative catalytic reaction (total …

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 …

Surface segregation with Pd enrichment, diminishing the desired characteristics of the Rh
species, remains as a key challenge for CZ (ceria-zirconia-based oxide)-supported Pd–Rh …

Selective catalytic reduction of NO x by NH3 (NH3-SCR) for diesel emission control at low
temperatures is still a great challenge due to the limit of the urea injection threshold and …

Ceria-zirconia based (CZ) materials are still a crucial component of three-way catalysts
(TWCs) now. Compared with traditional cubic or tetragonal phase, CZ material with …
