Bismuth Tungstate (Bi2WO6) that was prepared by solid-state reaction at high temperature in previous work showed catalytic activity in the degradation of organic compound under visible light irradiation. During the past three years, some reports on the fabrication of Bi2WO6 nano-/microstructures in solution and their use as visible-light photocatalysts have emerged. Despite much progress in this exciting...
In this paper, a low-temperature (T=70degC) solution-phase approach has been developed for the fabrication of vertically-aligned ZnO nanoneedle arrays directly on bulk nickel substrate. The synthetic process involving no seeds, no catalysts, and no surfactants can be readily scaled up. The as-grown ZnO arrays are further used for the first time as anode materials for Li-ion batteries operated in the...
