Abstract

Abstract Uniform porous anodized aluminum oxide (AAO) membrane has been synthesized by two-step anodization for fabricating tungsten trioxide (WO 3 ) nanowires. Under assayed conditions, uniform porous structure of alumina (Al 2 O 3 ) membrane with long range ordered hexagonal arrangements of nanopores was achieved. The self-assembled template possesses pores of internal diameter of 50 nm and interpore distance ( d int ) of 80 nm with a thickness of about 80 µm, i.e., used for fabrication of nanostructures. WO 3 nanowires have been fabricated by simple electroless deposition method inside Al 2 O 3 nanopores. SEM images show tungsten trioxide nanowire with internal diameter of about 50 nm, similar to porous diameter of AAO template. XRD results showed that nanowires exist in cubic crystalline state with minor proportion of monoclinic phase.
