Abstract
The structural effect on the addition of tin oxide to Ru02-Ti02 mixed oxide coatings has been presented. X-ray diffractior
patterns indicate a highly complex structure above 20%Sn02 in the ternary mixture. Considerable deviations in the Ru02
Ti02 structure do not occur below this limit. The electrical conductivity shows a linear dependence on the Sn02 content. The
morphology of the films changes from cracked-mud appearance to compact surface as the Sn02 increases; Higher overpoten.
tials shown by electrodes having Ru:Sn ratio in the range of 1.5 to 3.0 have been attributed to the presence of Sn atom!
at the surface. Lower crystallinity at higher Sn02 contents indicates a high surface area that may be responsible for thei~
enhanced oxygen evolution
