Process for preparing integrally-formed Ti4O7 ceramic electrode through TiC reduction
The invention provides a process for preparing an integrally formed Ti4O7 ceramic electrode through TiC reduction, which comprises the following steps: respectively weighing titanium dioxide, titanium carbide and a binder according to the mass ratio of titanium dioxide to titanium carbide to binder being (5-10): (1-1.5): 1, fully mixing, grinding, tabletting, sintering in an inert atmosphere, and cooling to obtain a product. The integrally-formed Ti4O7 ceramic electrode can be prepared through the method, the hardness of the integrally-formed Ti4O7 ceramic electrode is higher than that of a traditional ceramic electrode prepared with a carbon source as a reducing agent, the Ti4O7 prepared through the method is high in purity and reaction activity, the degradation rate of the Ti4O7 prepared through the method to reactive brilliant blue KN-R which is a high-concentration degradation-resistant organic pollutant reaches 79.59% under the condition that an industrial constant-current power source is powered on, and the Ti4O7 prepared through the method is suitable for industrial production. The method is easy to operate, high in safety, low in equipment requirement and free of vacuum environment, the production period can be shortened, the production cost can be reduced, and large-scale production and preparation can be carried out.
本发明提供了一种TiC还原制备一体成型的Ti4O7陶瓷电极的工艺，其中包括以下步骤：按质量比二氧化钛：碳化钛：粘结剂＝(5～10):(1～1.5)：1分别称取原料二氧化钛、碳化钛、粘结剂，充分混合并研磨，压片，然后在惰性气氛下烧结，冷却得到产品。本发明方法可制得一体成型的Ti4O7陶瓷电极，其硬度高于传统以碳源作为还原剂制备的陶瓷电极，并且本发明方法制备的Ti4O7纯度高，反应活性高，在工业所用恒流电源通电情况下，对高浓度难降解有机污染物活性艳蓝KN‑R的降解率达到79.59％，且本发明方法操作简单，安全性高，对设备要求低，无需真空环境，可缩短生产周期，降低生产成本，可进行大规模生产制备。
