Electro-catalysis electrode and preparing method and application thereof

The invention provides an electro-catalysis electrode and a preparing method and application thereof. The electro-catalysis electrode comprises a metal Ti base and an active substance layer located on the surface of the Ti base, the active substance layer is a compact layer formed by packing nano particles, the nano particles are made of doped SnO2, and the doping elements include F and Sb. The active substance layer of the electro-catalysis electrode is compact and free of cracks and is formed by packing the nano particles, the contact area between the electro-catalysis electrode and pollutants to be eliminated is increased, VOCs can be oxidized under the room temperature condition, the elimination rate reaches 100%, 80v% or more of the product is CO2, and the balance is a small amount of CO. In addition, the electro-catalysis electrode is simple in preparing method and easy to prepare. 本发明提供了种电催化电极、其制备方法及用途，所述电催化电极包括金属Ti基底，还包括位于Ti基底表面的活性物质层，所述活性物质层是由纳米颗粒堆砌而成的致密层，纳米颗粒的材质为掺杂的SnO，掺杂元素包括F和Sb。所述电催化电极的活性成分层致密无龟裂，
