A study is presented of the photoelectrocatalytic properties of films
of titanium dioxide that have been prepared by anodisation of titanium
metal in sulfuric acid. Films grown by galvanostatic control to a spe
cified cell voltage, followed by 'ageing' of the films under potentios
tatic control, have been used to oxidise water photoelectrocatalytical
ly. The corresponding anodic photocurrents have then been correlated w
ith the anatase crystallinity of the films, as determined by X-ray dif
fraction. The effect of thermal annealing on crystallinity and photoel
ectrocatalytic activity has also been examined.
