In this research, development of visible-light-driven photocatalysts has been conducted using a concept of nitrogen substitution for oxide photocatalysts without visible light response. Solid solutions between tantalum-based oxides and oxynitrides have been successfully synthesized. The obtained solid solution photocatalysts showed superior photocatalytic properties in comparison with the end-member oxynitride photocatalysts of them. Thus, it has been demonstrated that nitrogen substitution can be an efficient method to design new high-performance photocatalysts.

在本研究中，使用氮取代没有可见光响应的氧化物光催化剂的概念，进行了可见光驱动的光催化剂的开发。钽基氧化物和氮氧化物之间的固溶体已经成功地合成。与端元氮氧化合物光催化剂相比，所得到的固溶体光催化剂显示出上级的光催化性能。因此，它已被证明，氮取代可以是一种有效的方法来设计新的高性能的光催化剂。
