Oxygen reduction reaction (ORR) is regarded as the rate-determining step in a fuel cell or a
metal–air battery because of the kinetically retarded four-electron process. Among the …

In recent years, the field of catalysis has experienced an astonishing transformation, driven
in part by more demanding environmental standards and critical societal and industrial …

Perovskite oxides with formula ABO3 or A2BO4 are a very important class of functional
materials that exhibit a range of stoichiometries and crystal structures. Because of the …

The high cost and poor thermal durability of current lean nitrogen oxides (NO x)
aftertreatment catalysts are two of the major barriers to widespread adoption of highly fuel …

The diesel oxidation catalyst (DOC) has been part of diesel exhaust systems since
regulations were introduced to limit the amount of harmful emissions released to the …

Nitrogen oxides (mainly NO) are one of the major air pollutants that lead to a number of
environmental problems such as photochemical smog, acid rain and haze. The catalytic …

A series of structural modified LaxMnO3 (x= 0.9, 0.95, 1, 1.05, 1.11) perovskites used for NO
oxidation was synthesized by a sol–gel method and characterized by XRD, BET, XPS, EPR …

Due to the increasingly strict emission standards of NOx on various industries, many
traditional flue gas treatment methods have been gradually improved. Except for selective …

This article presents a systematic study of the formation and thermal stability of Pt oxide
species on size-selected Pt nanoparticles (NPs) supported on SiO2, ZrO2, and TiO2 thin …

Vehicular pollution has become a major problem in urban areas due to the exponential rise
in the number of automobiles. Typical exhaust emissions which include nitrogen oxides (NO …
