Rational Design and Synthesis of ZnWO<sub>4</sub> Nanorods Decorated with SnS Nanodots with Enhanced Visible-Light Photocatalytic Performance

Aiming to construct a direct Z-scheme binary heterostructure for efficient degradation of the organic dye Rhodamine B (RhB), ZnWO<sub>4</sub> nanorods decorated with SnS nanodots were rationally designed and prepared via a facile two-step route. Morphological observation and structural s...
