Tungsten diboride self-supporting electrode with porous net structure and preparation method and application of tungsten diboride self-supporting electrode
The invention belongs to the technical field of energy materials, and discloses a tungsten diboride self-supporting electrode with a porous net structure and a preparation method and application thereof. The preparation method comprises the following steps: firstly, synthesizing tungsten trioxide powder, boron carbide powder and carbon source powder into WB2 with a lamellar structure, taking the WB2 as a raw material, and mutually bonding lamellar grains into a net-shaped structure in a rapid sintering manner, so as to obtain a tungsten diboride bulk material with a porous net-shaped structure, which has high conductivity and can provide a larger electrochemical specific surface area; and more catalytic active sites are exposed.
本发明属于能源材料技术领域，公开了一种多孔网状结构的二硼化钨自支撑电极及其制备方法和应用。本发明首先将三氧化钨粉、碳化硼粉、碳源粉末合成具有片层状结构的WB2，以该WB2为原料，通过快速烧结方式将片层状晶粒相互粘结成网状结构，获得多孔网状结构的二硼化钨块状材料，具有高导电性，能提供更大的电化学比表面积，暴露出更多的催化活性位点。
