Oxide nanoparticles arrays are easily synthesized in a 3-steps method including (i) the deposition of poly(styrene)-b-poly(4-vinylpyridine) (PS-b-PVP) thin films, (ii) the selective deposition of inorganic precursors and (iii) the synthesis of oxide nanoparticles and the elimination of the polymer scaffold by thermal annealing. The specific staining of the PVP domains by inorganic precursors is obtained in this study thanks to a simple and fast spin coating process using an alcoholic solution of the precursors. This simple lab-procedure is used to synthesize a wide range of metallic (silicon, titanium, cerium, ruthenium, zinc and manganese) oxides, showing that this method can be extended to the synthesis of all kinds of oxides with all kinds of precursors as long as the precursor is soluble in P4VP solvent. It is shown that this strategy can be extended to the synthesis of oxide nanorods. (C) 2013 Elsevier Ltd. All rights reserved.
