Synthesis of hollow cubic Zn2SnO4 sub-microstructures with enhanced photocatalytic performance

Hollow cubic Zn2SnO4 sub-microstructures (ZTOs) were fabricated via a one-pot hydrothermal method. The samples were carefully characterized and the experimental results show that the as-prepared ZTOs possess hollow cubic morphology with the length of 500 nm and a relatively rough surface which may e...

Summary:Hollow cubic Zn2SnO4 sub-microstructures (ZTOs) were fabricated via a one-pot hydrothermal method. The samples were carefully characterized and the experimental results show that the as-prepared ZTOs possess hollow cubic morphology with the length of 500 nm and a relatively rough surface which may endow them high surface areas. The photocatalytic activities were evaluated by the degradation of methylene blue (MB), methylene orange (MO), and rhodamine B (RhB) and the results exhibit a much higher selectivity to the degradation of MB (95%) by Zn2SnO4 than that of MO (70%), RhB (81%) and ZnSn(OH)6 (MB 20%) in 20 min. [Display omitted] •Hollow cubic Zn2SnO4 were fabricated by a facile one-pot hydrothermal method.•The cubic morphology changed from smooth to roughly hollow surface by calcination.•Zn2SnO4 showed different selectivity on the photodegradation of RhB, MO and MB.•The calcination significantly influenced the photocatalytic activity of samples.
