Title: Self-assembled periodic nanoporous network in multifunctional ZrO{sub 2}-CeO{sub 2}-(La{sub 0.8}Sr{sub 0.2})MnO{sub 3} composites

Abstract

This letter reports the structural characteristics of the self-assembled surface nanostructure in the 0.75 wt % (Zr{sub 0.88}Ce{sub 0.12})O{sub 2}-0.25 wt % (La{sub 0.8}Sr{sub 0.2})MnO{sub 3} ceramics. The surface consists of periodic porous network with islandlike structures occurring at the triple boundary junctions. The pores were found to have the diameter in the range of 150-200 nm with the thickness of the porous surface layer of the order of 100 nm. The pore distribution was quasiperiodic with the spacing in the range of 50-150 nm. The formation of the nanoporous network is correlated to the structural transformation occurring in ZrO{sub 2} system.
