Outline of Final Research Achievements

To realize a sustainable society based on the solar-hydrogen production in the future, the development of novel photocatalytic materials is very important. In this work, we focused on the development of novel group-14 photocatalytic nitride materials, which have been designed on the basis of well-established and widely applied nitridosilicate materials.
Two representative new nitride systems, Na-alpha’-GeGaON and the solid solution of ZnGeN2-GaN have been successfully synthesized by utilizing the reduction-nitridation process developed, and their promising photocatalytic activities for hydrogen evolution have been demonstrated.
