CdS@MoS2 core@shell nanorod heterostructures for efficient photocatalytic pollution degradation with good stability

Abstract Solar-driven pollution-degradation is of a green approach to address the current environmental issues. However, impeded by the low-efficiency and poor-stability, the industrial application is still difficult to be realized. Herein, we developed a novel CdS@MoS2 core@shell nanoheterostructure with efficient and long-term stability toward RhB degradation, suggesting its potential applications. Detailed studies reveal the excellent performances can be attributed to the well-defined heterostructure and photocorrosion-resist of MoS2 shell. The demonstrated strategies in this work will pave a new pathway for overcoming the drawbacks of chalcogenide associated with their low-efficiency and poor-stability.
