Here we report a facile one-step low-temperature solution-based method to treat native TiO2 with NaH. The NaH treatment effectively induces the Ti(iii) species and oxygen vacancies into the TiO2 host lattice, and enables the absorption edge of TiO2 to be conveniently adjusted from the UV region to the red end of the visible spectrum.
在此，我们报道了一种简便的基于低温溶液的一步法，用于用NaH处理天然TiO₂。NaH处理有效地将Ti(iii)物种和氧空位引入TiO₂主体晶格，并使TiO₂的吸收边缘能够方便地从紫外区域调整到可见光谱的红色端。
