Abstract
As one of the most attractive and eco-friendly technologies, semiconductor photocatalysis is demonstrated as a potential strategy to solve global energy shortage environmental pollution problems. Regarding semiconductor-based photocatalysts, Zinc indium sulfide (ZnIn2S4) with various morphological structures has become research hotspots owing to its superior visible light absorption, high chemical durability and low cost. Nevertheless, the photocatalytic activity of pristine ZnIn2S4 is unsatisfactory due to limited range of visible light absorption and fast recombination rate of light-induced electrons and holes. Different modification strategies, such as metal deposition, element doping, vacancy engineering and semiconductor combination, have been systematically developed for enhancing the photocatalytic performance of ZnIn2S4 materials. In order to promote further developments of ZnIn2S4 in photocatalytic applications, this mini-review summarizes the progress of recent research works for the construction of highly activity ZnIn2S4-based photocatalysts for the first time. In addition, the typical applications of ZnIn2S4-based photocatalytic materials have been critically reviewed and described such as in hydrogen evolution from photocatalytic water splitting, carbon dioxide photoreduction, and treatment of water pollution. The current challenges and further prospects for the development of ZnIn2S4 semiconductor photocatalysts are finally pointed out.
