作者的目的是报告的光催化活性的最大增强的化学蚀刻锐钛矿型二氧化钛结晶玻璃。在晶化玻璃中进行了几种晶化行为和化学蚀刻条件的优化，以实现纳米结构陶瓷（NSC）。通过在结晶玻璃中的化学蚀刻的NSC制造是提供具有高比表面积的块体材料的最有效的解决方案之一。我们发现，在我们的玻璃体系中制备NSC作为一种新型的体相光催化剂的最佳条件，并获得了比未蚀刻的催化剂高16倍的催化活性。
The authors aim to report the largest enhancement of photocatalytic activity by chemical etching in anatase-type TiO2 crystallized glass. Optimization of several conditions for crystallization behavior and chemical etching to realize the nano-structured ceramics (NSC) has been performed in the crystallized glass. NSC-fabrication by chemical etching in the crystallized glass is one of the most effective solutions to provide bulk materials with high specific surface area. We have found that the best condition for the NSC fabrication as a novel bulk photocatalyst in our glass system, and have obtained 16 times higher catalytic activity than that of non-etched one.
