Bismuth oxide is another interesting material and its nanostructures show an enhanced photoelectrochemical performance [6,7]. However, the formation of bismuth nanostructures, such as bismuth oxide nanopores [6,7] or bismuth phosphate nanorods [8], by anodization is not well explored by now. Similar to the formation of nanoporous Al2O3 nanoporous Bi2O3 was produced in acidic, F--free electrolytes.
In this presentation, we demonstrate the anodization of bismuth in halide containing electrolytes similar to the electrolytes classically used for the formation of TiO2 nanotubes.
