摘要

采用X射线衍射法研究了RuO_2-SnO_2混合金属氧化物电极的相结构和晶格参数．结果表明：RuO_2和SnO_2形成了具有金红石型结构的固溶体．但与RuO_2-TiO_2电极比较，晶粒较为细小，因此涂层较致密．采用循环伏安法研究了电极的活性表面（q~*），结果显示，RuO_2-SnO_2电极具有较小的电极外表面和较大的电极内表面．上述结果有助于说明RuO_2-SnO_2电极稳定性提高的原因，同时也由于形成了更稳定的RuO_2-SnO_2化合物．

Abstract

The phase structure and lattice constants of RuO_2-SnO_2 mixed metal oxides electrode was investigated by XRD.It was found that mixed oxides system formed a solid solution of RuO_2- SnO_2 with a rutile- type structure

but it had a smaller crystalline size and more compact than the RuO_2-TiO_2 system. Cyclic voltammetry provided information about electrochemically active surface area（q）.The results indicated that for RuO- SnO_2 （associated with the external surface）was less and （associated with the internal surtface） was bigger than that of RuO_2-TiO_2. The enhancement of stability for Ru-Sn can be attributed to more compact oxide layer and the formation of a stable Ru-Sn compound.
