“…The lower the E a value, the easier is the complete oxidation of CH 4 over LSMO samples and, for this reason, higher catalytic activity. Table 4 [33], similar to those (51-79 kJ/mol) over 10-20 wt% LaCoO 3 /Ce 1−x Zr x O 2 (x = 0-0.2) [34]. As a result, the findings of kinetic studies approve that the 3DOM LSMO samples demonstrated excellent catalytic activity for the CH 4 combustion, and it is a promising catalyst for the combustion of CH 4 in practical application.…”

Catalytic combustion of CH 4 is significant for power generation and environment protection. Perovskite-type oxides (ABO 3 ), A is typically an alkaline earth and B a transition-metal ion [1][2][3][4][5][6]. Unfortunately, the traditional methods (e.g., solid-state reaction [7], sol-gel [8], coprecipitation [9], and polymerizable complexing [10]) are concerned in high-temperature reaction, bring about the damaging of pore structures, and consequently show low BET (<10 m 2 /g). This problem can be resolved by means of colloidal crystal templating (CCT) route, by which one can create a threedimensionally ordered 3DOM structure. The colloidal crystal template is fabricated by ordering monodispersed microspheres (poly methyl methacrylate (PMMA) or silica) into a face-centered close-packed array [11]. With PS microbeads as template, Sadakane et al. [12][13][14] . In previous chapter, we fabricated 1D LSCO nanowire materials with high BET without using the surfactant-templating. In this chapter, we compare result of 1D to 3D catalyst as well as investigate on surfactant-assisted PMMA method. The use of a template can give increase to the invention of porous structure on the wall of skeletons. Note that some of the 3DOM catalysts showed brilliant catalytic activity in the combustion of CH 4 , therefore enhancing the physical and chemical properties of the catalysts. Based on this new idea, we have developed a novel and facile dimethoxytetraethylene glycol (DMOTEG) PMMA-templating route, in order to be able to synthesize 3DOM La 0.6 Sr 0.4 MnO 3 (3DOM LSMO) with nanovoid-like or mesoporous walls. In this chapter, we report the characterization, preparation, and performance activity of CH 4 combustion of 3DOM LSMO with nanovoid-like or © Springer-Verlag Berlin Heidelberg 2015 H.

“…In the last years much attention has been paid to the perovskite-type ceramic oxides, ABO 3 (A is usually rare earth and B is transition metal [23][24][25][26][27]), and to the spinel ferrite-type oxides, MFe 2 O 4 (M is divalent metal ion) [28][29][30][31] as promising combustion catalysts mainly due to their excellent thermal stability properties, low cost and easy processing. Moreover, the structural stability of the perovskites allows for the partial substitution of A and/or B by other metal that can improve their catalyst properties.…”
