Sodium-ion batteries (SIBs) have received much attention, owing to their great potential for large-scale application. A lack of efficient anode materials with high reversible capacity is one main challenge facing the development of SIBs. Antimony- and bismuth-based chalcogenides materials can store large amounts of Na ions, owing to the alloying/dealloying reaction mechanism within a low potential range, and thus, are regarded as promising anodes for SIBs. However, these materials face great challenges of poor ion diffusion rate, multiple phase transformations, and severe morphology pulverization. Herein, recent developments in antimony- and bismuth-based chalcogenides materials, mainly rational structural design strategies used and the electrochemical reaction mechanisms involved, are summarized. Perspectives for further improving antimony- and bismuth-based chalcogenides anodes are also provided.

Article Synopsis
- Antimony (Sb) pollution in water poses serious health risks, prompting research into effective decontamination methods.
- A new bismuth-based photocatalyst, BiO(OH)(AsO) (BOHAs), was developed, showing significantly higher rates of Sb(III) removal compared to other photocatalysts.
- The study findings indicate that BOHAs maintain high efficiency over multiple cycles and can also target organic pollutants, suggesting a promising strategy for improving water decontamination processes.

Owing to the exterior self-trapped excitons (STEs) with adjustable fluorescence beams, low-dimensional ns-metal halides have recently received considerable attention in solid-state light-emitting applications. However, the photoluminescence (PL) mechanism in metal halides remains a major challenge in achieving high efficiency and controllable PL properties because the excited-state energy of ns conformational ions varies inhomogeneously with their coordination environments. Here, a novel zero-dimensional (0D) lead-free bismuth-based RbBiCl·0.

Antimony/bismuth-based lead-free hybrid halide defect 2D perovskites have been generating enormous research interest due to their inherent excellent optical properties. Exploration of new phases and understanding of their structural and optoelectronic properties are of paramount importance in the process of developing materials for practical solar cell applications. In this article, we have reported a structural transition from the 0D hexagonal phase containing isolated [MI] (M = Bi/Sb) units to the 1D orthorhombic phase via a new monoclinic phase with novel isolated trimeric [MI] units in (CHNH)BiSbI.
