“…LSCrF10 shows an increment of the Cr(VI) oxidized species with respect to the undoped LaCrO 3 ( Table 2). The increase of Cr(VI) with the insertion of Sr in the structure was previously reported [22]. For the other Sr and Fe doped perovskite oxides, LSCrF1030 and LSCrF1050, the relative percentage of Cr(VI) detected on the surface is comparable to that of LaCrO 3 ( Table 2).…”

“…By performing a peak-fitting deconvolution, the O 1 s spectra can be separated into two peaks. The lower binding energy one around 529.2 eV could be attributed to lattice oxygen O 2- [34,35], denoted as O b , whereas the second, less intense peak around 530.5 eV is assigned to surface adsorbed oxygen, CO 3 2-or OH - [34,36], referred as O a . The ratios of O a /O b in Table 2 show an increase in Reaction and Characterization of Co and Ce doped Mn/TiO 2 catalysts for low-temperature SCR… chemical adsorbed oxygen after doping of Co, and a further increase of chemical adsorbed oxygen after co-doping of Co and Ce.…”

The catalysts of cobalt and cerium doped Mn/TiO 2 were tested for low-temperature selective catalytic reduction of NO with NH 3 , and these samples were characterized by XRD, XPS, Raman, H 2 -TPR and NH 3 -TPD methods. The catalytic activity results showed that the NO x conversion was obviously improved by Co and Ce doping. Ternary metal oxide catalyst Mn-Co-Ce/TiO 2 exhibited the highest catalytic activity of 99 % at 423 K. The XRD and Raman analysis indicated formation of MnO 2 or CoMnO 3 phases on Mn/TiO 2 and Mn-Co/TiO 2 . The XPS results demonstrated that the metal cations existed mainly in the form of Mn 4? , Co 2? and Ce 4? , respectively. XPS and H 2 -TPR results supported the presence of Mn-Co mixed oxides. Doping of Ce could enhance dispersion of Mn-Co oxides on the surface. Addition of Co and Ce led to higher surface Mn 4? /Mn 3? ratio, chemisorbed oxygen, acidity and dispersity, which enhanced NH 3 adsorption and oxidation of NO to NO 2 , subsequently, the NO x reduction was accelerated through the Fast SCR reaction.

“…Traditionally, perovskite-type oxides were prepared by solid state reaction of oxides and/or carbonates [22][23][24]. However, such a traditional method possesses the disadvantages of long processing time, low surface area, large particle size, and limited degree of chemical homogeneity.…”

The decomposition of La[Fe(CN) 6 ] and La [Co(CN) 6 ] under different atmospheres has been analyzed by thermogravimetry (TG) and differential thermal analysis (DTA). In addition, the decomposition temperature at different sample locations was monitored for sample masses around 2 g of La[Fe(CN) 6 ] and La[Co(CN) 6 ], when they were calcined for 1 h at temperatures ranging from 200 to 400 ºC in a controlled gas-flow system.Results showed that, for sample large enough of these cyano complex precursors undergo combustion when are decomposed under oxygen atmosphere. X-ray diffraction 2 revealed that perovskite-type oxides crystallize due to the overheating of the process. As a result, it has been possible to produce LaFeO 3 and LaCoO 3 perovskite-type oxide powders by SHS under oxygen atmosphere using La[Fe(CN) 6 ] and La[Co(CN) 6 ] as a precursor. The effect of the ignition temperature has been investigated. The specific surface area of the perovskite-type oxides produced via SHS using heteronuclearcyano metal complex as a precursor is significantly higher than that of other LaMO 3 produced using the same technique but obtained from other type of precursors.
