文摘

•: K_1.6Ca₂Nb₃O_9.4N_0.6·1.1H₂O oxynitride was synthesized by ammonolysis of KCa₂Nb₃O₁₀.
•: The oxynitride showed good stability even after a long time of exposure to air.
•: The material was protonated and exfoliated into nanosheets with good cristallinity.
•: These nanosheets are potential building blocks to new nanostructured materials.
•: The band gap makes these materials promising photocatalysts with visible radiation.
