The reaction of NO+C3H6+O2 over the mesoporous SBA-15 supported transition metal catalysts

Composite formation in CdSe:Cu2Se nanocrystal films, charge transport characteristics and heterojunction performance

“…The intensities of Cu 2p 3/2 and the Cu 2p 1/2 peaks increased as the Cu 2 Se wt% 41,42 Satellite peaks at 940 and 945 eV of Cu 2+ oxidation state reported in the literature were absent in the spectra of the samples CS5 and CS20. [43][44][45][46] The absence of satellite peaks of Cu 2+ ruled out the possibility for +2 oxidation state of Cu in the present samples. The AFM images of nanocrystal thin lms of CdSe:Cu 2 Se containing different Cu 2 Se wt% of 5, 10, 20 and 30% are shown in Fig.…”

Selective Catalytic Reduction of Nitric Oxide with Propylene over Fe/Beta Catalysts Under Lean-Burn Conditions

“…At nearly the same iron content, Fe/Beta(LIE) catalyst exhibited superior catalytic activity than other catalysts, indicating that the preparation method might lead to the different distribution of iron species, which was an important factor affecting C 3 H 6 -SCR activity. Furthermore, Fe/Beta(LIE) catalyst in the present case has shown higher HC-SCR activity than other Fe-based zeolite catalysts reported in the literatures (e.g., Fe/ZSM-5 [15], Fe/MFI [32], Fe/SBA-15 [33]), probably due to the Beta zeolite had better adsorption property of hydrocarbons than other zeolites [34].…”

Comparative study of ZSM‐5 supported transition metal (Cu, Mn, Co, and Fe) nanocatalysts in the selective catalytic reduction of NO with NH3

“…This might be related to that manganese species are more easily reducible than iron and cobalt species, according to the TPR‐profiles (see Figure ). In short, the redox properties are crucially responsible for the NO reduction by NH 3 likely via facilitating the corresponding reduction and/or oxidation process (e.g., preoxidation of NH 3 , nitrite or nitrate formation) .…”
