Abstract: As a renewable and environmentally friendly energy conversion technique, photocatalytic technology has a wide range of potential uses. Because of their suitable energy band structure and exceptional light-absorbing capacity, CdS materials exhibit significant promise in photocatalysis. However, challenges like the high rate of photogenerated carrier complexes and photocorrosion limit the practical application of CdS materials. Building composite heterostructures can help address the drawbacks of CdS materials. Of them, NiFe-LDH is the ideal material to enhance CdS's photocatalytic activity due to its layered structure, high stability, and large number of active sites. This review highlights the great potential of the CdS/NiFe-LDH heterostructure in the photocatalytic field by reviewing the fundamental properties of CdS and NiFe-LDH, as well as the preparation process, photocatalytic mechanism, and applications in the fields of carbon dioxide reduction, organic pollutant degradation, and photocatalytic hydrogen precipitation. The future development direction of this heterostructure and the difficulties (material stability, preparation cost, etc.) in practical application are finally discussed in this work. Future studies should focus on improving the properties of the substance and creating more effective preparation techniques in order to support its broad application in clean energy and environmental preservation and to lay the foundation for the industrial use of CdS/NiFe-LDH heterostructures.
