Preparation of porcupine-like Bi2O3 needle bundles by anodic oxidation of bismuth
Original language description
A 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 degrees C in air, tetragonal beta-Bi2O3 was produced without any morphological change.
