Synthesis of LaAlO3 based materials for potential use as methane-fueled solid oxide fuel cell anodes

Proposition of a Mechanism for the Electrochemical Oxidative Coupling of Methane

“…Moreover, the CSOFC reactor herein treated and supported by previous work [1,2] makes viable the application of this technology for the co-generation of chemicals (C 2 -type hydrocarbons), heat and electric energy from the direct utilization of methane. The electrocatlysts synthesizing methods necessary for the present case have been developed [3].…”

Effects of Sr and Mn co-doping on microstructural evolution and electrical properties of LaAlO3

“…Since the electrical conductivity of LaAlO 3 is significantly affected by adding appropriate dopants, systems based on LaAlO 3 are known to be mixed ionic and p-type electronic conductors at high oxygen partial pressure and good ionic conductors at low oxygen partial pressure. These materials have also low cost, higher stability in different types of atmospheres, and moderate thermal expansion, which make them adequate for SOFC applications [7][8][9][10][11].…”

Materials for a New Paradigm of the Chemistry Industry

“…It comprises a multifunctional anode fabricated with new ceramic materials that simultaneously present catalytic and electrocatalytic activities for the oxidative coupling of methane. Recently [7], the synthesis of these materials was described, with the use of the Pechini method to obtain ceramic powder with nanometric sized particles, that are utilized to fabricate the ceramic suspension with which the anode is deposited by screen-printing. The specific chemical composition of the ceramic inorganic nanometric particles, with a perovskite structure, their controlled addition in a solvent with other elements that include dispersants, plasticizers and pore formers to obtain an anode ceramic suspension and the calcination and sintering heat treatments, are necessary procedures to reach the anode microstructure, porosity and tortuosity required for an efficient SOFC operation.…”
