Desalination remains a key strategy for addressing water shortages, and solar-driven interfacial evaporation offers an economically viable approach. However, the slow rates of evaporation have hindered its widespread adoption. In this study, three-dimensional (3D) evaporators showed superior performance in enhancing water delivery and reducing heat loss compared to two-dimensional (2D) steam generation systems. The evaporation rate of the 3D steam generator, which is composed of a GO/PVA aerogel composite, was significantly higher, reaching 2.37 kg m h. This value is 1.96 times greater than that of the prepared 2D GO film evaporator. Additionally, it demonstrates outstanding reliability and consistency in salt resistance cycling tests. This advancement in evaporation technology opens up new possibilities for scaling up desalination processes and treating wastewater, thereby holding significant potential to alleviate global water scarcity challenges.
