Abstract:
Photoelectrolysis of water, first reported in 1972 by Fujishima and Honda [1], has recently attracted renewed interest since it offers a renewable, non-polluting approach to hydrogen production [2, 3] . Interest in semiconductor photoanodes made of the titanium dioxide, which is characterized as highly stable against photocorrosion and is relatively inexpensive, has renewed. Thus, a possibility to manufacture nanostructured photoanodes, owing to high surface area and improved charge separation kinetics, became basic direction of the investigations [4-7]. The aim of this work was the manufacture of semiconductor photoanodes made of thin-film titanium oxide by anodization of pure titanium plates at an invariable voltage and investigation of their photoelectrochemical properties.
