| Research Abstract |
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.
