Abstract
Porous alumina template was prepared by constant voltage in three different electrolytes (0.45 M sulfuric acid,
0.3 M oxalic acid, and mixed solution of 0.45 M sulfuric and 0.3 M oxalic acids). In this paper, the effects of the
electrolyte type on the morphology is studied, so the anodization is carried out in an oxalic acid, sulfuric acid, and a
mixture of oxalic and sulfuric acids. The effect of these three different electrolytes was investigated by scanning
electron microscopy. Results show that in sulfuric acid, the pore structure is smaller than the oxalic and a mixture of
oxalic and sulfuric acid. Density of holes in sulfuric acid was higher than other electrolytes; however, arrangement
of pores in oxalic acid was more regular than that of the others.
