Sulfur vacancy-rich ZnIn2S4 nanosheet arrays for visible-light-driven water splitting

Jie Chen et al.

Summary: In this study, ZnIn2S4 nanosheet arrays (NSAs) were synthesized and sulfur vacancies were introduced on the surface through plasma treatment. The enhanced photoelectrochemical (PEC) performance of ZnIn2S4, including increased photocurrent and H-2 evolution rate, was attributed to improved visible light absorption and carrier separation, as well as the trapping effect of the sulfur vacancies. This work presents a novel strategy for enhancing the PEC hydrogen evolution of ZnIn2S4.

Universal machine learning framework for defect predictions in zinc blende semiconductors

Arun Mannodi-Kanakkithodi et al.

Summary: We propose a framework powered by machine learning and high-throughput density functional theory computations for screening functional impurities in zinc blende semiconductors. By considering different elements as impurities at different sites, we create a chemical space of approximately 12,000 points and use a DFT dataset to train machine learning models for predicting impurity formation energies and charge transition levels. The optimized models can screen impurities with lower formation energy than dominant defects.

A mini-review on ZnIn2S4-Based photocatalysts for energy and environmental application

Guping Zhang et al.

Summary: Semiconductor photocatalysis is considered as an attractive and eco-friendly technology for addressing global energy shortage and environmental pollution. Zinc indium sulfide (ZnIn2S4) has gained research attention due to its excellent visible light absorption, high chemical durability, and low cost. However, the photocatalytic activity of pristine ZnIn2S4 is limited by its narrow visible light absorption range and fast recombination rate of electrons and holes. Various modification strategies have been developed to enhance the photocatalytic performance of ZnIn2S4 materials. This review summarizes recent progress in the construction of highly active ZnIn2S4-based photocatalysts and critically reviews their applications in hydrogen evolution, carbon dioxide photoreduction, and water pollution treatment. The current challenges and future prospects for ZnIn2S4 semiconductor photocatalysts are also discussed.
