The success of photocatalysis in different applications majorly depends on the efficiency or activity of the catalysts used in the visible light region. Although, several photocatalysts have been reported to be efficient in various photocatalytic applications, bismuth-based chalcogenides are one of the compounds with unique performance. This is because they possess band gap energies that allow them to absorb radiation in the visible light region of the solar spectrum. They are non-toxic, photostable, photoactive, re-usable, and are chemically or biologically inert. The preparation of bismuth-based chalcogenides involves the incorporation of oxides, sulphides, selenides and tellurides onto the bismuth compound in order to develop different photocatalysts. The various synthesis procedure for bismuth containing compounds are discussed extensively. Both the chemical and physical properties of these photocatalysts, with their possible morphological forms are highlighted. Furthermore, the challenges associated with their synthesis and photocatalytic applications are discussed, in addition to their respective mechanisms of action.

光催化在不同应用中的成功主要取决于可见光区域中使用的催化剂的效率或活性。尽管已经报道了几种光催化剂在各种光催化应用中是有效的，但是基于铋的硫属化物是具有独特性能的化合物之一。这是因为它们具有带隙能量，可以吸收太阳光谱的可见光区域中的辐射。它们是无毒的，耐光的，光活性的，可重复使用的，并且具有化学或生物惰性。铋基硫属化物的制备涉及将氧化物，硫化物，硒化物和碲化物掺入到铋化合物上，以开发出不同的光催化剂。广泛讨论了含铋化合物的各种合成方法。这些光催化剂的化学和物理性质，以及它们可能的形态形式都得到了强调。此外，除了它们各自的作用机理外，还讨论了与其合成和光催化应用相关的挑战。
