New materials belonging to the La2Srn-2TinO3n+1 system have been targeted as having the potential to provide suitable materials for high performance anode applications in solid oxide fuel cells. These compounds can be regarded as an intergrowth of two different structures, viz. distorted pyrochlore (La2Ti2O7) and perovskite (SrTiO3). By synthesising intergrown structures between the above two end members, it is possible to follow the evolution of the system from monoclinic through to cubic phases.
