Novel ceramic catalytic electrode and preparation method thereof
The invention discloses a novel ceramic catalytic electrode and a preparation method thereof. The novel ceramic catalytic electrode comprises a catalytic electrode ceramic matrix and precious metals arranged in the catalytic electrode ceramic matrix and on the surface of the catalytic electrode ceramic matrix, the catalytic electrode ceramic matrix is porous ceramic with tiny three-dimensional pore channels in the interior and on the surface, and the precious metals are distributed in the porous ceramic in a three-dimensional net shape. One purpose of the invention is to provide a novel ceramic catalytic electrode with low cost and high performance. The number of three-phase interfaces among precious metal, porous solid electrolyte ceramic and oxygen is greatly increased due to the structure, so that the novel ceramic catalytic electrode also has excellent catalytic capability under the condition of using a small amount of precious metal, and the production cost is greatly reduced. Another purpose of the invention is to provide a preparation method of the novel ceramic catalytic electrode, and the ceramic electrode prepared by the method is simple in process operation, good in combinability of the electrode material and the ceramic substrate, and less in precious metal consumption.
本发明公开了一种新型陶瓷催化电极及其制备方法，所述新型陶瓷催化电极包括催化电极陶瓷基体和设置于所述催化电极陶瓷基体内部和表面的贵金属，所述催化电极陶瓷基体为内部和表面具有微小立体孔道的多孔陶瓷，所述贵金属在所述多孔陶瓷内呈立体网状分布。本发明目的之一是提供一种低成本、高性能的新型陶瓷催化电极，其结构极大增加贵金属、多孔固体电解质陶瓷与氧气之间三相界面的数量，从而在使用少量贵金属的情况下，所述新型陶瓷催化电极也具有优良的催化能力，很大程度的降低了生产成本。本发明的另一目的在于提供一种新型陶瓷催化电极的制备方法，该方法制备的陶瓷电极工艺操作简单，电极材料与陶瓷基体的结合性好，贵金属用量少。
