Bismuth-based semiconducting photocatalysts have received more and more attentions due to their suitable band gap for visible light response, rich varieties, availability, and potential applications in photocatalysis areas including hydrogen evolution from water splitting, refractory pollutant removal, organic synthesis, and so on. Since photocatalysis belongs to a heterogeneous reaction, the surface structure characteristics of photocatalysts play a crucial role in the photocatalytic performance, which is dependent on preparation techniques. Various strategies have been proposed for the preparation of bismuth-based photocatalysts with desirable structure and morphology. The same preparation methods with slight conditions change may lead to different microstructures and properties, or vice versa. This review comparably summarize the development in the preparation strategies of bismuth-based photocatalysts particles, and especially, analyzes reaction process and formation mechanism to various microstructures, aiming to provide help and guidelines for future work.

铋基半导体光催化剂由于其能带隙适合可见光响应，丰富的品种，可利用性以及在光催化领域的潜在应用而受到越来越多的关注，这些领域包括水分解产生的氢，难降解的污染物去除，有机合成等。 。由于光催化属于非均相反应，因此光催化剂的表面结构特征在光催化性能中起着至关重要的作用，这取决于制备技术。已经提出了各种策略来制备具有期望的结构和形态的铋基光催化剂。条件稍有变化的相同制备方法可能导致不同的微观结构和性能，反之亦然。本文综述了铋基光催化剂颗粒制备策略的发展，特别是分析了各种微观结构的反应过程和形成机理，旨在为今后的工作提供帮助和指导。
