摘要：

Nanostructured parallelly oriented TiO2 micropillar arrays, either pure or implanted on a carbon matrix, are prepared via controlled oxidation of hybrid carbonaceous systems. Mild oxidation at 500 degrees C (O-2 1%) leads to formation of parallelly oriented elongated TiO2 pillars, which emerge from a compact alpha-C phase (TiO2/C composite). Under strong oxidation conditions (O-2 10%) formation of pure TiO2 pillar arrays is observed.
