Ru-Sn　binary　oxide　is　one　of　the　most　frequently　used　anode　coating　material　in　electrochemical　industry,　but　its　composition　distribution　and　microstructure　are　not　homogeneous,　so　the　nanoscale　RuO2-SnO2　binary　oxide　was　prepared　for　improvement　by　a　sol-gel　technique.　The　morphology,　microstructure,　crystal　structure　and　other　properties　of　the　new　oxide　were　studied　by　EPMA,　DTA,　XRD,　TEM,　and　electrochemical　analysis.　The　results　showed　that　the　Ru-Sn　oxide　nanomaterial　has　excellent　electrocatalytical　properties.
