Construction of Embedded Heterostructured SrZrO₃/Flower-like MoS₂ with Enhanced Dye Photodegradation under Solar-Simulated Light Illumination.

ABSTRACT: SrZrO₃/flower-like MoS₂ composites with an embedded heterostructure were synthesized via a simple two-step hydrothermal method and their performance was evaluated by photodegradation of methylene blue (MB) under solar-simulated light irradiation. The sandwiched flower-like MoS₂ with a high Mo(VI) ratio was adopted as the matrix, and SrZrO₃ was grown between the MoS₂ layers, forming an intense contact interface, which promotes the efficient separation and transport of photoinduced carriers. The enhanced photocatalytic degradation of 99.7% after 80 min of irradiation is exhibited over the MS5 sample (5 wt % SrZrO₃ loading amount on the MoS₂ matrix). Moreover, the ratio of Mo(VI) and the superoxide radical plays a cr
