Abstract: 

WE REVIEW THE FABRICATION AND PROPERTIES OF TIO2 NANOTUBE ARRAYS MADE BY ANODIC OXIDATION OF TITANIUM IN FLUORIDE-BASED ELECTROLYTES. THE MATERIAL ARCHITECTURE HAS PROVEN TO BE OF GREAT INTEREST FOR USE IN WATER PHOTOELECTROLYSIS AND PHOTOCATALYSIS. WE EXAMINE THE ABILITY TO FABRICATE NANOTUBE ARRAYS OF DIFFERENT SHAPE (CYLINDRICAL, TAPERED), PORE SIZE, LENGTH, AND WALL THICKNESS BY VARYING ANODIZATION PARAMETERS INCLUDING ELECTROLYTE CONCENTRATION, PH, VOLTAGE, AND BATH TEMPERATURE, WITH FABRICATION AND CRYSTALLIZATION VARIABLES DISCUSSED IN REFERENCE TO A NANOTUBE ARRAY GROWTH MODEL. WE REVIEW EFFORTS TO LOWER THE BAND GAP OF THE TITANIA NANOTUBES BY ANIONIC DOPING. THE ARTICLE CONCLUDES BY EXAMINING VARIOUS PRACTICAL APPLICATIONS OF THE REMARKABLE MATERIAL ARCHITECTURE, INCLUDING ITS USE FOR WATER PHOTO ELECTROLYSIS.
