An　IrO2-Ta2O5/Ti　anode　coating　with　molar　ratio　of　Ir　to　Ta　of　7:3　on　titanium　was　prepared　by　a　modified　technology,　in　which　a　portion　of　nano-crystalline　of　IrO2　was　introduced　to　replace　some　amount　of　H2IrCl6　in　the　precursor　solution.　The　phase　structure　and　morphology　of　the　coating　were　analyzed　by　X-ray　diffractometry　(XRD)　and　scanning　electronic　microscopy　(SEM),　respectively.　The　electro-catalytic　properties　and　electrochemical　stability　of　the　coating　were　also　characterized　by　using　O2　evolution　polarization,　cyclic　voltammetry　(CV)　test　and　accelerating-life　test,　respectively.　The　results　show　that　the　crystallite　phases　of　the　nano-seeds　embedded　electrode　coating　are　IrO2-based　solid　solution　(Ir,　Ta)O2　and　IrO2　phase.　In　addition,　the　anodes　with　the　nano-seeds　embedded　coatings　exhibit　better　electro-catalytic　activity　and　corrosion　resistance　compared　with　the　IrO2-Ta2O5/Ti　anodes　prepared　by　the　traditional　method.
