The effects of excess manganese in nano-size lanthanum manganite perovskite on enhancement of trichloroethylene oxidation activity

Synergetic effects of plasma and metal oxide catalysts on diesel soot oxidation

“…The first peak is referred to the adsorbed oxygen bound to the vacancies of surface anions and is more mobile. The latter peak is attributed to the more strongly bound oxygen species [48]. The O 2 -TPD profile of Co 3 O 4 is shown in Fig.…”

Fluorescent magnetic nanoparticles for cell labeling: Flux synthesis of manganite particles and novel functionalization of silica shell

“…This problem has not previously been reported; although the preparation of LSMO particles via MSS has been attempted in several previous studies [25,26,40,41], sufficient characterization to reveal amorphous components has not previously been performed. It is worth noting that Maghsoodi et al have recently reported the preparation of La-manganite with an intentional excess of Mn via a sol-gel process followed by annealing at 600°C [42]. The authors presented the XRD patterns of a seemingly single-phase perovskite manganite, but their TEM micrographs clearly revealed the presence of an amorphous phase, which was interpreted as a manganese oxide.…”

Combination of non-thermal plasma and Pd/LaMnO3 for dilute trichloroethylene abatement

“…Their high catalytic activity is attributed to the presence of stable mixed valence states in the ''B" site, the availability of weakly bonded oxygen at the surface and the presence of crystal lattice defects [6,9,10]. Moreover, perovskites are cheaper than noble metal catalysts and are more effective due to their superior thermal stability and lower poisoning by sulfur, phosphorus and halogen [11].…”

“…Perovskite type catalysts (ABO 3 , A = La, Y and B = Ni, Co, Fe, Mn) are known to be among the most active catalysts for the oxidation of chlorinated VOCs (CVOCs) [6][7][8]. Their high catalytic activity is attributed to the presence of stable mixed valence states in the ''B" site, the availability of weakly bonded oxygen at the surface and the presence of crystal lattice defects [6,9,10].…”
