Recent Progress in Anodic Oxidation of TiO₂ Nanotubes and Enhanced Photocatalytic Performance: A Short Review

By adjusting the oxidation voltage, electrolyte, anodizing time and other parameters, TiO 2 nanotubes with high aspect ratio can be prepared by in organic system because anodic method has advantage of simple preparation process, low material cost controllable morphology. This review focusses on influence parameters morphology nanotube arrays anodizing. In order to improve photocatalytic activity under visible light prolong life photo-generated carriers, research status improving recent years is reviewed. modification oxidation, which helpful understand best structure appropriate methods, thus guiding application practical photocatalysis. Finally, development prospected.
