Combustion synthesis of LaMn1−xAlxO3+δ (0 ≤ x ≤ 1): tuning catalytic properties for methane deep oxidation

Ni-substituted LaMnO3 perovskites for ethanol oxidation

“…Since coking is less likely to occur under oxygen-rich environments, agglomeration of catalyst particle and/or deconstruction of perovskite structure should be responsible for catalyst deactivation. 64 The SEM micrographs of freshly prepared and used LaMn 1Ày Ni y O 3 aer on-stream testing (see Fig. S7 of ESI †) further supported this claim: some welding and particle agglomeration could be identied on used samples; however, no carbon deposition (e.g., carbon nanotubes) was specied.…”

High specific surface area LaMO3(M = Co, Mn) hollow spheres: synthesis, characterization and catalytic properties in methane combustion

“…In addition, the mean grain sizes of the samples were estimated using the Debye-Scherrer equation. The crystallite size of LM-5 is 16.8 nm, which is much smaller than other LaMnO 3 , 23,24 suggesting that carbon sphere template method can greatly reduce the crystallite size. The EDX images of LM-1 to LM-6 are shown in Fig.…”

Complex Catalytic Materials Based on the Perovskite-Type Structure for Energy and Environmental Applications

“…520 • C and increases with the Al content. Notably, the T 50 value decreases with the increase of the SSA, the highest SSA (22 m 2 /g) corresponding to the La(Mn 0.9 Al 0.1 )O 3 system [250]. Recently, Miao et al [251] reported a catalyst based on La(Mn,Fe)O 3 with an excellent stability at 550 • C in the catalytic combustion of methane.…”
