Solar-driven interfacial water evaporation is regarded as an effective, renewable, and environment-friendly technology for clean water production. However, bio-fouling caused by the nonspecific interaction between the steam generator and bio-foulants, generally hinders the efficient application of wastewater treatment. Herein, this work reports a facile strategy to fabricate flexible anti-biofouling fibrous photothermal membrane consisting of MXene coated cellulose membrane for efficient solar driven water steam generation toward water purification applications. The as-prepared MXene/cellulose photothermal membrane exhibits light absorption efficiency as high as ~94% in a wide solar spectrum range and a water evaporation rate up to 1.44 kg/m-2 h-1 under one solar illumination. Also, the MXene/cellulose membrane shows very high antibacterial efficiency (above 99.9%) owing to the MXene coating as a highly effective bacteriostatic agent. Such a flexible, anti-biofouling and high-efficiency photothermal membrane sheds light on practical applications in long-term wastewater treatments.
