Preparation method of Ti4O7 ceramic electrode
The invention provides a preparation method of a Ti4O7 ceramic electrode. The preparation method comprises the following steps: S1, preparing a precursor anatase type TiO2 substrate sheet; and S2, performing high-temperature reduction in an H2 atmosphere to prepare the Ti4O7 ceramic electrode. The Ti4O7 prepared by the method is stable in performance, high in purity, free of a titanium oxide passivation layer on the surface, high in reaction activity and relatively strong in absorption effect in a visible spectrum region, the degradation rate of the Ti4O7 on a refractory organic pollutant reactive brilliant blue KN-R under visible light reaches 75.28%, the method is simple to operate, the production period is shortened, the production cost is reduced, and the large-scale preparation is easy.
本发明提供一种Ti4O7陶瓷电极的制备方法，包括以下步骤：S1、前驱体锐钛矿型TiO2基体片的制备；S2、在H2气氛下高温还原制得Ti4O7陶瓷电极。本发明方法制备的Ti4O7性能稳定，纯度高，表面没有氧化钛钝化层，反应活性高，在可见光谱区具有较强的吸收效果，在可见光下对难降解有机污染物活性艳蓝KN‑R的降解率达到75.28％，并且本发明方法操作简单，缩短了生产周期，降低了生产成本，易于大规模制备。
