The global shortage of freshwater resources and the energy crisis have propelled solar-driven interfacial evaporation (SDIE) coupled with photocatalytic technology to become a research focus in efficient low-carbon water treatment. Graphene-based materials demonstrate unique advantages SDIE–photocatalysis integrated systems, owing their broadband light absorption, ultrafast thermal carrier dynamics, tunable electronic structure, low enthalpy characteristics. This review systematically investigates enhancement mechanisms graphene photothermal conversion on processes, including (1) improving absorption through surface morphology modulation, defect engineering, plasmonic material compositing; (2) reducing via hydrophilic functional group modification porous structure design; (3) suppressing heat loss insulation layers 3D structural optimization; (4) enhancing transport efficiency fluid channel engineering wettability control. Furthermore, salt resistance strategies optimization significantly improve system practicality stability. In treatment applications, graphene-based SDIE systems achieve synergistic “adsorption–catalysis–evaporation” effects, enabling degradation organic pollutants, reduction in/fixation heavy metal ions, microbial inactivation. However, practical implementation still faces challenges steam condensation efficiency, insufficient long-term durability, high scaling-up costs. Future should prioritize mass transfer optimizing environmental adaptability, developing low-cost manufacturing processes promote widespread application systems.
