dc.description.abstractA new Bi2O3 structure resembling bundles of needles was prepared by anodic oxidation of a bismuth substrate in H2SO4 electrolyte followed by annealing in air. Needle growth occurred on the timescale of minutes. The resulting porcupine-like needle bundles were characterized using SEM and XRD before and after annealing. The as-grown needles consisted of bismuth aqua sulfate hydroxide; however, upon annealing at 250 °C in air, tetragonal β-Bi2O3 was produced without any morphological change.cze
