中文摘要：

这里，我们报导一条热水的途径在多重层次规模下面造并且定制 brookite TiO ₂ 水晶的层次结构。得益于层次结构和氧空缺的存在，这些同样准备的层次 brookite TiO ₂ 晶体不能仅仅提高 photocatalytic 活动，而且在表面的恶意的肿瘤的处理表明他们的潜力。

英文摘要：

Here we report a hydrothermal approach to build and tailor the hierarchical structure of brookite TiO2 crystal under multiple hierarchical scales. Benefiting from the hierarchical structure and the existence of oxygen vacancy, these as-prepared hierarchical brookite TiO2 crystals can not only enhance photocatalytic activity, but also demon- strate their potential in the treatment of superficial malig-nant tumor.
