Abstract Solar‐driven interfacial evaporation is a promising technology for freshwater production from seawater, but salt accumulation on the evaporator surface hinders its performance and sustainability. In this study, we report simple green strategy to fabricate three‐dimensional porous graphene spiral roll (3GSR) that enables highly efficient solar evaporation, collection, water near‐saturated brine with zero liquid discharge (ZLD). The 3GSR design facilitates energy recovery, radial transport, directional crystallization, thereby resulting in an ultrahigh rate of 9.05 kg m −2 h −1 25 wt% under 1‐sun illumination 48 continuously. Remarkably, crystallization outer not only enlarges area also achieves collection 2.92 , thus enabling ZLD desalination. Additionally, exhibits record‐high 3.14 outdoor test. This innovative solution offers continuous desalination method treatment, which has great implications addressing global scarcity environmental issues arising disposal.
