Abstract: Photocatalytic technology is one of the effective means to solve environmental pollution, energy crisis and microbial purification, which has been widely used and developed rapidly in the semiconductor field. Among them, Bi₂MoO₆ has become a research hotspot in the field of photocatalysisdue to its strong visible light response performance and narrow band gap. However, the practical application of Bi₂MoO₆ is limited due to poor chemical surface morphology and slow carrier migration rate. Previous studies have proved that morphology adjustment is an effective method to enhance the photocatalytic performance of bismuth. In this paper, the research progress of morphology control and application of Bi₂MoO₆ photocatalyst in recent years was summarized, including morphology classification, preparation methods and applications. In addition, the factors affecting the morphology of Bi₂MoO₆ were also discussed, including reaction time, temperature, and pH value of the solution. Finally, the research direaction and challenges of Bi₂MoO₆ morphology control were proposed.
