In recent years, the semiconductor bismuth oxide (Bi2O3) has attracted increasing attention as a potential visible-light-driven photocatalyst due to its simple composition, relatively narrow bandgap (2.2–2.8 eV), and high oxidation ability with deep valence band levels. Owing to the symmetry of its unit cell, Bi2O3 exists in more than one crystal form and exhibits phase-dependent photocatalytic properties. However, the phase-selective synthesis of Bi2O3 is a complex process, and its phase transformation usually occurs in a wide temperature range. Therefore, the development of Bi2O3 phases with a controllable microstructure and good photocatalytic properties is a great challenge. Hundreds of articles have been reported on the phase-selective synthesis and photocatalytic performance of Bi2O3. However, an interacting and critical review has rarely been reported, and thus it is essential to fill the gap in the literature. In this review, the phase-dependent photocatalytic performance of Bi2O3 is presented in detail. The phase-selective synthesis and temperature-dependent phase stability of highly active Bi2O3 are explored. The phase junction in Bi2O3 is reviewed, and the future perspective with an outlook on contemporary challenges is provided finally.

多晶型 Bi2O3 的制备、微观结构和光催化性能综述
近年来，半导体氧化铋（Bi 2 O 3）由于其组成简单、带隙相对较窄（2.2-2.8 eV）以及具有深价态的高氧化能力，作为一种潜在的可见光驱动光催化剂受到越来越多的关注。乐队水平。由于其晶胞的对称性，Bi 2 O 3以不止一种晶型存在并且表现出相依赖的光催化性能。然而，Bi 2 O 3的相选择性合成是一个复杂的过程，其相变通常发生在很宽的温度范围内。因此，开发Bi 2 O 3具有可控微观结构和良好光催化性能的相是一个巨大的挑战。关于Bi 2 O 3的相选择性合成和光催化性能的文章已有数百篇报道。然而，互动和批判性评论很少被报道，因此填补文献中的空白是必不可少的。在这篇综述中，详细介绍了 Bi 2 O 3的相依赖性光催化性能。探索了高活性Bi 2 O 3的相选择性合成和温度依赖性相稳定性。Bi 2 O 3 中的相结 回顾，最后提供了对当代挑战的未来展望。
