摘要：

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.
