The invention relates to the technical field of capacitive deionization, in particular to a preparation method and application of a NiCoS-PBA/g-C3N4 composite material. The method comprises the following steps: preparing a NiCo-PBA precursor from nickel salt, cobalt salt, sodium citrate and potassium ferricyanide through a coprecipitation method; preparing NiCoS-PBA from the NiCo-PBA precursor in a mode of chemical etching and a mode of hydrothermal synthesis; the preparation process is simple, and large-scale industrial preparation is easy. The NiCoS-PBA/g-C3N4 composite material prepared by the method disclosed by the invention has high desalting capacity when being used as a CDI electrode material for desalting. The NiCoS-PBA and melamine are mixed and then calcined, and the NiCoS-PBA/g-C3N4 composite material is obtained. 本发明涉及电容去离子技术领域，特别是涉及一种NiCoS-PBA/g-C3N4复合材料的制备方法及应用。该方法包括以下步骤：将镍盐、钴盐、柠檬酸钠和铁氰化钾通过共沉淀法制备NiCo-PBA前驱体；将所述NiCo-PBA前驱体通过化学刻蚀和水热合成的方式制备NiCoS-PBA；本发明制备过程简单，易于大规模工业化制备。利用本发明方法制备得到的NiCoS-PBA/g-C3N4
