Title: Self-assembled cabbage-like NaInS{sub 2} microstructures with efficient visible light photocatalytic performance

Cabbage-like NaInS{sub 2} microstructures have been synthesized by reacting In(NO{sub 3}){sub 3} with the alkaline sulfur aqueous solution of NaOH in a simple hydrothermal process without any shape-directing surfactants. The cabbage-like NaInS{sub 2} 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 NaInS{sub 2} architectures is discussed. The cabbage-like NaInS{sub 2} 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 NaInS{sub 2} architectures is mainly due to their special surface areas and inner interconnected structural features. - Graphical abstract: Cabbage-like NaInS{sub 2} microstructures were facilely synthesized via simple hydrothermal reaction. The cabbage-like NaInS{sub 2} architectures exhibit the superiority of photocatalytic performance for the photodegradation of RhB irradiation under visible light irradiation. - Highlights: • Cabbage-like NaInS{sub 2} microstructures were facilely synthesized via a hydrothermal reaction. • Influencing parameters on the NaInS{sub 2} morphologies have been discussed in detail. • The cabbage-like NaInS{sub 2} architectures hold efficient photocatalytic performance. • The photocatalytic superiority is mainly due tomore » their special structural features.« less
