文摘

Cabbage-like NaInS₂ microstructures have been synthesized by reacting In(NO₃)₃ with the alkaline sulfur aqueous solution of NaOH in a simple hydrothermal process without any shape-directing surfactants. The cabbage-like NaInS₂ architectures are monodispersed in large quantities. The cabbage-like morphologies depend strongly on the different ratios of S powder to NaOH, the reaction temperature and reaction time. The possible growth mechanism for the formation of cabbage-like NaInS₂ architectures is discussed. The cabbage-like NaInS₂ architectures exhibit the superiority of photocatalytic performance for the photodegradation of RhB irradiation under visible light irradiation. It is believed that the photocatalytic superiority of the cabbage-like NaInS₂ architectures is mainly due to their special surface areas and inner interconnected structural features.
