英文摘要	The performance of particulate photocatalysts for solar H-2 production highly depends on the unique morphology and tailored shape. Herein, we successfully fabricated a highly crystalline BaTaO2N crystal with a plate-like structure from a K2CO3-KCl binary flux under a nitridation atmosphere. The fabricated platy BaTaO2N was characterized, and the results as well as formation mechanism were discussed accordingly. Owing to the generation of oxo-complex [TaO3](-) by the assistance of CO32- and the lattice match of the BaTaO2N (111) plane with the Ba5Ta4O15 (001) plane, the platy BaTaO2N crystals with well-developed {111} facets were formed via the simultaneous formation and transformation of Ba5Ta4O15. Upon optimization of the molar ratio of K2CO3 and KCl, an excellent photocatalytic performance for H-2 evolution was obtained at the molar ratio of 20/80 due to the plate-like structure and high crystallinity of the BaTaO2N photocatalyst. This finding provides a facile approach for the fabrication of shape-controlled and highly crystallized (oxy)nitride photocatalysts aimed at efficient solar H-2 production.
