Porous anodic alumina has been produced on aluminium substrate of different manganese content by single-step anodizing at 50V in 0.3M oxalic acid at 15°C for 60 minutes. The well-ordered pore and cell structure was revealed by subjecting the porous anodic alumina to oxide dissolution treatment in a mixture of chromic acid and phosphoric acid. It was found that the manganese content above 1wt impaired the regularity of the cell and pore structure significantly, which can be attributed to the presence of secondary phases in the starting material with manganese content above 1wt. The pore diameter and interpore distance decreased with the addition of manganese into the substrates. The time variation of current density and the thickness of porous anodic alumina also decreased as a function of the manganese content in the substrates. 2014-02-25T04:51:50Z 2014-02-25T04:51:50Z 2012 Article Journal of Nanomaterials, vol. 2012, 2012, pages 1-9 1687-4110 http://www.hindawi.com/journals/jnm/2012/752926/ http://dspace.unimap.edu.my:80/dspace/handle/123456789/32146 en Hindawi Publishing Corporation
