| Annotation | Over the past few decades, tremendous efforts have been invested in creating low-cost, non-toxic, stable, and potent photocatalysts. Cesium lead halides perovskites (CsPbX3) have garnered significant attention in photocatalysis due to their excellent optoelectronic properties, like high absorptivity, distinctive defect tolerance and tunable bandgap. This class of materials has shown remarkable efficiency in facilitating solar-driven reactions, including organic pollutant degradation, water splitting, CO2 reduction, and organic synthesis. The incorporation of cesium cations enhances the structural stability and optoelectronic properties of lead halide perovskites, leading to improved photocatalytic performance. Although cesium lead halides perovskites are more stable compared to organic-inorganic lead halides perovskites, CsPbX3 are highly sensitive to environmental factors and can break down when they come into contact with air, light, humidity, and heat. In this mini-review, the crystal structure of CsPbX3 perovskites, performance in photocatalytic organic pollutant degradation, and demonstrating the importance of stability through encapsulation, nanocomposite formation, doping, and heterostructure development are discussed. Some problems and outline prospects of CsPbX3 in this field are also discussed. By delving into these aspects, this work aims to contribute to the ongoing efforts in developing robust photocatalytic systems that can effectively mitigate environmental pollution. |
