Abstract The integration of solar‐driven interfacial evaporation and electricity co‐generation is considered a promising approach to simultaneously alleviate freshwater scarcity the energy crisis. However, affected by intermittent solar irradiation/uncontrollable weather, overall performance in real world greatly reduced. Herein, inspired antifreeze proteins beetles that survive extreme climates, all‐weather evaporators with sandwich structure are designed. top bottom layers composed MnO 2 ‐modified cotton cloth used for photothermal conversion water transport, meanwhile, middle layer made phase change microcapsule/hydrogel composite serves heat storage release. Under 1 kW m −2 irradiation, evaporator exhibits high rate 2.67 kg h −1 an efficiency 89.5%. In dark, released from supports 0.43 , 3.6 times pure water. Additionally, assembled thermoelectric module, hybrid device achieves stable output power 0.42 W under 1‐sun illumination prolonged 30 min dark. This work provides novel full‐time solar‐powered steam‐electricity proof concept biomimetic steam generation/heat management integration.

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.

Solar-driven interfacial evaporation provides a promising pathway for sustainable freshwater and energy generation. However, developing highly efficient photothermal photocatalytic nanomaterials is challenging. Herein, substoichiometric molybdenum oxide (MoO3–x) nanoparticles are synthesized via step-by-step reduction treatment of l-cysteine under mild conditions simultaneous conversion reactions. The MoO3–x low degree decorated on hydrophilic cotton cloth to prepare MCML evaporator toward rapid water production, pollutant degradation, as well electricity obtained has strong local light-to-heat effect, which can be attributed excellent the surface plasmon resonance effect in heat loss evaporator. Meanwhile, rich area localized together effectively accelerate degradation reaction antibiotic tetracycline. With benefit these advantages, attains superior rate 4.14 kg m–2 h–1, admirable efficiency 90.7%, adequate 96.2% 1 sun irradiation. Furthermore, after being rationally assembled with thermoelectric module, hybrid device employed generate 1.0 W electric power density. This work presents an effective complementary strategy production sewage generation remote off-grid regions.
