In this article, silver nanowires (AgNWs) were prepared and introduced into the double-layer photoanode of dye-sensitized solar cells (DSSCs). Silver with a diameter about 50–60 nm length 1–2 mm by polyol method. The power conversion efficiency DSSC made AgNWs@TiO2 AgNPs@TiO2 composite materials is 6.38%. Compared unmodified DSSC, combined AgNWs AgNPs increased 58.7%. This was mainly due to loc...

cofe/cu multilayer nanowires were electrodeposited into anodic aluminum oxide templates prepared by a two-step mild anodization method, using the single-bath technique. nanowires with 30 nm diameter and the definite lengths were obtained. the effect of cofe layers thickness and annealing on the magnetic behavior of the multilayer nanowires was investigated. the layers thickness was controlled t...

The Fe nanowires were prepared by Ac electrodeposition method. The two steps anodized aluminum oxides (alumina) were used as templates for electrodeposition of magnetic nanowires. Sulfuric acid was used to anodize aluminum. The pours diameter and growth rate of alumina were investigated. The FeSO4 electrolyte was used for growth of nanowires. The prepared magnetic nanowires were characterized b...

Photocatalysis is proven to be the most efficient and environmentally friendly method for degradation of organic pollutants in water purification. To meet requirement large-scale treatment, there are two important points: One lifetime chemical stability photocatalyst material, especially complex harsh aqueous conditions. The other ease synthesis such photocatalysts with specific nano-morphology...

This study reports the fabrication of n-TiO2/p-Si hetrojunction by deposition of TiO2nanowires on p-Si substrate. The effect of system pressure and the current-voltage (I-V) characteristics of n-TiO2/p-si hetrojunction were studied. The morphology of the samples was investigated by Field Emission Scanning Electron Microscopy (FESEM) which confirms formation of T...

TiO2 nanomaterials with controlled morphologies have attracted extensive interest because of potential applications in solar energy conversion, environmental cleanup and hydrogen generation. Nanoscale titanium dioxides have been produced as nanotubes, nanosheets, nanowires and mesoporous microspheres by a variety of approaches. Among the various nanomaterials, mesoporous microspheres have drawn...

Electric vehicles and grid storage devices have potentialto become feasible alternatives to current technology, but only if scientists can develop energy storage materials that offer high capacity and high rate capabilities. Chemists have studied anatase, rutile, brookite and TiO2(B) (bronze) in both bulk and nanostructured forms as potential Li-ion battery anodes. In most cases, the specific c...
