Some　binary　RuO　2-SnO　2　oxides　coated　on　Ti　were　synthesed　by　the　thermal　decoposion　method.　A　remarkable　behaviour　of　pseudo-capacitance　has　been　shown　on　the　cyclic　voltmmograms　of　the　prepared　samples.　It　is　concluded　that　the　poor　specific　capacitance　has　been　found　for　both　RuO　2-enriched　and　SnO　2-enriched　binary　oxides.　The　maximum　specific　capacitance　occurs　at　the　composition　of　40　mol%　SnO　2　and　reaches　the　value　of　1080Fg　-1　when　this　electrode　was　annealed　at　the　temperature　of　260°C.　The　addition　of　Sn　into　the　binary　oxide　coating　can　help　improve　the　electrode　capacitancee　and　do　no　harm　to　the　electro-catalytic　properties.　Copyright　©　Taylor　&　Francis　Group,　LLC.
