CuO Nanotubes Synthesized by the Thermal Oxidation of Cu Nanowires

摘要: Copper oxide (CuO) is a narrow band-gap semiconducting that has been widely used as cathode in dye-sensitized solar cells, gas sensors and heterogeneous catalysts. Much effort devoted to synthesizing unique CuO nanostructures, such as, rods, wires, ribbons, cubes, spheres dandelions. Unlike nanorods nanowires, only few groups have synthesized nanotubes due fabrication difficulties within hollow nanowires. were by pyrolyzing copper acetylacetonate the pores of anodic alumina membranes. average length 100 nm also hydrothermal process involving microemulsified Cu(OH)42−.12 The simplest method making from direct thermal oxidation metal, many research prepared nanowires oxidizing foils. However, self aggregation, it difficult obtain long nanowire or nanorod precursors for preparation oxidation. Here, we describe simple morphologies produced determined scanning electron microscopy transmission microscopy.
