Title
Synthesis, characterization and CO oxidation of TiO2/(La,Sr)MnO3 composite nanorod array
Abstract

Ordered TiO2/(La,Sr)MnO3 composite nanorod array catalysts have been successfully fabricated by using a combination of hydrothermal synthesis and radio-frequency (RF) magnetron sputtering method on Si and glass substrates. Electron microscopy, energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and Brunauer–Emmett–Teller (BET) method are used to characterize the structure, morphology, composition and surface area of the as-prepared nanorod arrays. The TiO2/(La,Sr)MnO3 core–shell nanorod arrays exhibit an enhanced CO oxidation activity compared to TiO2 nanorods, which might be due to the lattice oxygen in (La,Sr)MnO3. The TiO2/(La,Sr)MnO3 composite nanorod array may provide a promising class of nanocatalysts for energy and environment applications.

Composite nanorod arrays are better nanocatalysts for CO oxidation than TiO2 nanorod arrays. ► (La,Sr)MnO3 nanoshell enhances CO oxidation performance as a result of lattice oxygen defects.
