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 …

Alumina materials, as one of the cornerstones of the modern chemical industry, possess
physical and chemical properties that include excellent mechanical strength and structure …

Abstract Diesel Oxidation Catalyst (DOC) is an effective device to reduce engine emissions.
To improve the oxidation performance of HCs, NO x and CO, a 3D simulation model of …

Efficiently treating methane emissions in transportation remains a challenge. Here, we
investigate palladium and platinum mono-and bimetallic ceria-supported catalysts …

Lattice oxygen in metal oxides plays an important role in the reaction of diesel oxidation
catalysts, but the atomic-level understanding of structural evolution during the catalytic …

Manganese oxides with different valences (MnO 2, Mn 2 O 3 and Mn 3 O 4) synthesized by a
hydrothermal synthesis method were investigated to evaluate their catalytic performances …

We present a facile selective dissolution method for the surface modification of SmMn2O5
mullite (SMO) to increase the exposed sites for NO oxidation on the premise of excellent …

With tightening emission regulations and the advent of Zero-Carbon targets, curbing
emissions from engines has become imperative. To enhance the emissions reduction of …

Recently copper ion-exchanged LTA zeolites were proved to be robust for NH 3-SCR
reaction. In this study, Cu/LTA catalysts with Si/Al= 15 and Cu/Al= 0.4 were synthesized via …

Nanofiber catalysts are potentially promising to be equipped in the lean-burned vehicle
exhaust emission system considering its facile synthesis, low-cost, long durability in contrast …
