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.

Solar photothermal-driven interfacial evaporation is a promising technology with great potential for wastewater purification and seawater desalination. However, intermittent solar illumination salt accumulation are still the major roadblocks of in practical applications. Herein, we developed novel system based on hierarchical MXene/polydopamine (PDA)/magnetic phase-change microcapsule composites (hereafter named "MXene/PDA@TiO2/Fe3O4@C22-HMC") integrated natural wood. The were fabricated by microencapsulating n-docosane as material (PCM) core TiO2/Fe3O4 composite shell then coating PDA layer, followed surface-attaching MXene nanosheets. obtained MXene/PDA@TiO2/Fe3O4@C22-HMC exhibits good optical absorption ability, high heat energy-storage capacity, hydrophilicity. This enables MXene/PDA@TiO2/Fe3O4@C22-HMC-based evaporator to gain water rate 2.09 kg m-2 h-1 under one-sun illumination. A combination microchannels wood tiny gap between microcapsules results rapid transportation within system, which effectively resists during evaporating process. As result, there was no crystal observed from surface 10 wt % NaCl solution three-sun 8 h. More importantly, introduction Fe3O4 nanoparticles into TiO2 endows magnetism, greatly enhancing reusability separability undertake multicycle washing processes long-term desalination use. latent release offers large amount energy continuous semi-cloudy day, increasing total production 1.17 compared conventional without PCM. study provides an effective utilization solar-driven systems
