A hybrid catalytic system comprised of metal oxide and Cu or Fe exchanged zeolite
components represents a potential advancement of state-of-the-art for selective catalytic …

Developments in ceria-based soot oxidation catalysts, especially during the last decade, are
reviewed. Based on the comparisons of the activity, durability and cost-efficiency of different …

Oxygen vacancy (O-vacancy) is essential in catalytic oxidation but little is known about its
insight. Herein, a series of MnO x-CeO 2 catalysts with various Mn/(Mn+ Ce) molar ratios …

Co3O4 is a well-known catalyst in the oxidation reaction. In such a catalyst, the geometric
and electronic structures of tetrahedrally coordinated Co2+ and octahedrally coordinated …

Surface species and oxygen vacancies were studied in MnO x (0.4)-CeO 2 toward repeated
soot oxidation. MnO x (0.4)-CeO 2 catalysts prepared by the citric acid complex method were …

Low temperature propane oxidation has been achieved by Co 3 O 4-based nano-array
catalysts featuring low catalytic materials loading (15 mg under flow rate of 150 mL/min). The …

The relative efficacies of zirconium and lanthanum promoters in ceria solid solutions were
investigated systematically for low temperature soot oxidation. Thus nanosized CeO2–ZrO2 …

To reduce the emissions of internal combustion engines, ceria-based catalysts have been
widely investigated as possible alternatives to the more expensive noble metals. In the …

Nanometric CeO2-supported cobalt oxide materials with variable Co/Ce atomic ratios were
prepared by the method of ultrasonic-assisted incipient-wetness impregnation. The catalytic …

The effect of different dopants including niobium, iron, tungsten and zirconium oxide on the
low-temperature activity of MnOx–CeO2 catalysts for the selective catalytic reduction (SCR) …
