Mini‐Review: Progress on the Controllable Synthesis of Micro/Nanoscale Bi2S3 Functional Materials

Abstract Bismuth sulfide (Bi 2 S 3 ) with micro/nanostructures as an important semiconductor material has attracted considerable attention due to its high ionic conductance, high photoelectric conversion efficiency, and large absorption coefficient, which is widely applied in the areas of photocatalysis, energy conversion, sensors, biomedicine, and pollutant disposal. Up to now, various strategies are reported for the morphology‐controlled synthesis of micro‐nanoscale Bi 2 S 3 and Bi 2 S 3 ‐based materials via manipulating the thermodynamics and kinetics in the chemical fabricating process. However, the Bi 2 S 3 with designed shapes still remains to be developed to well adapt these diverse usages. To conclude, the designed preparation strategies, advanced applications, current challenges, and future expectations of Bi 2 S 3 are discussed to provide some potential suggestions for further promotion of Bi 2 S 3 functional materials.
