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
