Near-Infrared Light Driven ZnIn(2)S(4)-Based Photocatalysts for Environmental and Energy Applications: Progress and Perspectives

Zinc indium sulfide (ZnIn(2)S(4)), as a significant visible-light-responsive photocatalyst, has become a research hotspot to tackle energy demand and environmental issues owing to its excellent properties of high stability, easy fabrication, and remarkable catalytic activity. However, its drawbacks, including low utilization of solar light and fast photoinduced charge carriers, limit its applications. Promoting the response for near-infrared (NIR) light (~52% solar light) of ZnIn(2)S(4)-based photocatalysts is the primary challenge to overcome. In this review, various modulation strategies of ZnIn(2)S(4) have been described, which include hybrid with narrow optical gap materials, bandgap engineering, up-conversion materials, and surface plasmon materials for enhanced NIR photocatalytic performance in the applications of hydrogen evolution, pollutants purification, and CO(2) reduction. In addition, the synthesis methods and mechanisms of NIR light-driven ZnIn(2)S(4)-based photocatalysts are summarized. Finally, this review presents perspectives for future development of efficient NIR photon conversion of ZnIn(2)S(4)-based photocatalysts.
