Summary:The present invention relates to a method for making a tubular anodic aluminum oxide with nanometer or sub-micron pores. The mainly method was used an electrolytic polishing and anodization formation pore structure of anodic aluminum oxide on the tubular aluminum substrate. After further removal of part of the aluminum substrate, available on a tubular aluminum anodic aluminum oxide with both sides of the aluminum tube was available. The arrangement of the holes varies with the purity of the aluminum substrate. The pores grow on the poor purity of the aluminum substrate of 6061 aluminum; on the other hand, ordering pores grow on the high purity aluminum substrate; for example 99.999% (5N) aluminum. The tubular anodic aluminum oxide with a pore structure can be further applied to the carrier material required for energy conversion, photo-catalyst, or high order filtration.
