Porous Tin Oxides Prepared Using an Anodic Oxidation Process

Open, porous structures of tin oxides, fabricated by an anodic oxidation process, are characterized by irregular channels with diameters of several tens of nanometers, as shown in the Figure. The as-prepared amorphous tin oxides can be transformed by annealing to a crystalline stannic structure with very few micro-structural changes. The materials may find applications in batteries and chemical sensors.
