Porous Perovskite Materials in Catalysis

Editorial Perovskite-type oxides with the general formula ABO3 containing both rare earth elements and 3d transition metals have received intensive attention in recent years due to their wide range of applications in adsorption, separation, catalysis, and sensors. In terms of the heterogeneous catalysis, the reaction always involves diffusion and adsorption of reactants on the surface of catalyst, surface reaction of adsorbed species and desorption of products. Clearly, the reactions happened on the surface of catalyst; therefore making surface area as a critical factor to determine the availability of catalytic sites. Consequently, heterogeneous catalysis can be improved through the incorporation of improved specific surface area via engineered porosity in a solid catalyst. Hence, new strategies and technologies are continuously being developed for the synthesis and structure-tailoring of high surface area of mesoporous materials.
