“…BiOI has excellent oxygen storage and releases capabilities because of its large number of oxygen vacancies. [203] A straightforward hydrothermal approach was successfully used to produce BiOCl micro-assembles consisting of ultrafine nanoplates with a platelike appearance and a spherical shape. To generate an air cathode, ultrafine nanoplates were incorporated into BiOCl micro-assembles.…”

Aluminum air batteries (AABs) are a desirable option for portable electronic devices and electric vehicles (EVs) due to their high theoretical energy density (8100 Wh K−1), low cost, and high safety compared to state‐of‐the‐art lithium‐ion batteries (LIBs). However, numerous unresolved technological and scientific issues are preventing AABs from expanding further. One of the key issues is the catalytic reaction kinetics of the air cathode as the fuel (oxygen) for AAB is reduced there. Additionally, the performance and price of an AAB are directly influenced by an air electrode integrated with an oxygen electrocatalyst, which is thought to be the most crucial element. In this study, we covered the oxygen chemistry of the air cathode as well as a brief discussion of the mechanistic insights of active catalysts and how they catalyze and enhance oxygen chemistry reactions. There is also extensive discussion of research into electrocatalytic materials that outperform Pt/C such as nonprecious metal catalysts, metal oxide, perovskites, metal‐organic framework, carbonaceous materials, and their composites. Finally, we provide an overview of the present state, and possible future direction for air cathodes in AABs.

“…Theoretical calculations have shown that the CB of bismuth-based compounds mainly consists of Bi 6p orbits [163]. Therefore, an increase in the bismuth content in BiOX can shift the CB to a more negative potential, hence, intensifying the photocatalytic reduction [201].…”

“…From our points of view, monolayered 2D BiOX and 2D BiOX nanosheets with selective exposure of specific crystal facet are expected to exhibit particularly outstanding photocatalytic activity. And the research on the application of monolayered 2D BiOX in green energy such as photocatalytic water splitting [209] and storage batteries [201,272,273] will lead the next wave of research on BiOX.…”

Bismuth-based binary compounds, including Bi2Se3 and Bi2Te3, have attracted increasing attention as well-known topological insulators. On the other hand, bismuth-based ternary compounds exhibit diverse properties, such as, ultrahigh carrier mobility, and strong Rashba spin splitting. Moreover, they boast of superior photocatalytic properties, implying great potential to be used in a wide range of applications. The unique structure and properties of two-dimensional (2D) materials, especially the extraordinary electronic and optical properties of 2D Bi2O2Se, have given rise to significant research interests for the exploration of 2D bismuth-based ternary compounds. In this review, we will comprehensively discuss the properties of three important families of bismuth-based ternary compounds, including Bi2O2X (X = S, Se, Te), BiTeX (X = Cl, Br, I), and BiOX (X = Cl, Br, I). In particular, we have placed emphasis on the latest progress in their 2D forms, including their novel properties and applications. This review would aid in understanding the superior performance of bismuth-based ternary compounds and offer a perspective for future research on these emerging 2D materials.
