摘要Two-step anodizing technology (TSAT) has been used widely in the assembling process of porous anodic alumina and porous anodic TiO2 nanotubes. However, the theoretical background and foundation of TSAT are still unclear because of the ambiguous interpretations about the pore generation. A detailed introduction to the origin and theoretical foundation of the TSAT and imprinting technology is presented. The unexplainable experiment phenomena in two-step anodizing process which traditional theories (e.g. the field-assisted dissolution or ejection) can not explain and the limitation and using conditions of the TSAT and imprinting technology are analyzed. The explanation for these conflicting phenomena reported in the published references is given via the oxygen bubbles model. The important effect of the oxygen bubbles mould and the viscous flow of barrier oxide on the formation of columnar and regular channels is emphasized. The electronic current, ionic current and oxygen bubble mould will play an important role in the structural modulation of porous anodic alumina and porous anodic titania nanotubes. The present views may be helpful to understand the mechanism of porous anodic titania and facilitate the assembling of diverse nanostructures for extensive application in photocatalysis and solar batteries.
