“…In recent years, solar-driven interfacial water evaporation has received increasing attention as a practical water purification solution for water-scarce regions [ 152 , 153 ]. In comparison with traditional desalination technologies, solar evaporation systems demonstrate high-efficiency, low-cost, and eco-friendly performances [ 154 ]. MXenes with 2D nanosheet morphology and strong photo absorption capacity from UV to infrared (IR) range are excellent candidates for the fabrication of solar evaporators [ 152 ].…”

Highlights Fabrication, characterizations and photothermal properties of MXenes are systematically described. Photothermal-derived antibacterial performances and mechanisms of MXenes-based materials are summarized and reviewed. Recent advances in the derivative applications relying on antibacterial properties of MXenes-based materials, including in vitro and in vivo sterilization, solar water evaporation and purification, and flexible antibacterial fabrics, are investigated. Abstract The pernicious bacterial proliferation and emergence of super-resistant bacteria have already posed a great threat to public health, which drives researchers to develop antibiotic-free strategies to eradicate these fierce microbes. Although enormous achievements have already been achieved, it remains an arduous challenge to realize efficient sterilization to cut off the drug resistance generation. Recently, photothermal therapy (PTT) has emerged as a promising solution to efficiently damage the integrity of pathogenic bacteria based on hyperthermia beyond their tolerance. Until now, numerous photothermal agents have been studied for antimicrobial PTT. Among them, MXenes (a type of two-dimensional transition metal carbides or nitrides) are extensively investigated as one of the most promising candidates due to their high aspect ratio, atomic-thin thickness, excellent photothermal performance, low cytotoxicity, and ultrahigh dispersibility in aqueous systems. Besides, the enormous application scenarios using their antibacterial properties can be tailored via elaborated designs of MXenes-based materials. In this review, the synthetic approaches and textural properties of MXenes have been systematically presented first, and then the photothermal properties and sterilization mechanisms using MXenes-based materials are documented. Subsequently, recent progress in diverse fields making use of the photothermal and antibacterial performances of MXenes-based materials are well summarized to reveal the potential applications of these materials for various purposes, including in vitro and in vivo sterilization, solar water evaporation and purification, and flexible antibacterial fabrics. Last but not least, the current challenges and future perspectives are discussed to provide theoretical guidance for the fabrication of efficient antimicrobial systems using MXenes.

“…[44,45] Nevertheless, efficient yet continuous desalination also requires a basic anti-salt-blocking structure. [46][47][48] For example, the Janus evaporators, [49,50] millimeter-scale perforated evaporators, [51,52] and nanofiber-based evaporators [53] have overcome the salt accumulation upon evaporation. Regrettably, until now, the evaporator with simultaneously anti-biofouling, anti-oilfouling, and salt-rejecting properties is rarely reported.…”

Solar steam generation has emerged as an environment-friendly and promising strategy to overcome the freshwater and energy crisis. However, simultaneously attaining the satisfied evaporation rate, durability and energy utilization in a single system is challengeable, but crucial to the practical application. Herein, inspired by the carpet weaving technique and benefiting from "fiber-yarn-fabric" hierarchical structures, a 3D fabric evaporator with vertical hemp-yarn arrays is innovatively constructed, featuring a combined structure of multiscale pores from tunable spacing between adjacent fibers or yarns, the vertically aligned architecture coated with superhydrophilic MXenesandwiched layer and the adjustable side height/areas. These structures work cooperatively, surprisingly achieving the integrated functions of excellent light capture, the balanced evaporation area and vapor escape space, the additional energy adsorption from the environment and the salt exchange along or between micro/macro pores. Consequently, the 3D evaporator exhibits an outstanding evaporation rate (3.95 kg m −2 h −1 under one-sun illumination) and extremely high outdoor evaporation (47.04 kg m −2 for 8 h), accompanied with outstanding salt-resistance (continuous 120 h in 14% brine without salt accumulation), anti-oilfouling and anti-bacterial (efficiency over 99.9%) performances. Finally, through rationally assembling multi-function modules with a condenser, an all-in-one "desalination-thermoelectricity-irrigation" platform is built, realizing the maximum utilization of steam condensation enthalpy.

“…The ion concentration of the freshwater obtained through SIE can meet the World Health Organization standard for drinking water without further treatment. [11][12][13] Besides, the SIE of wastewater such as dye wastewater, heavy metal wastewater, oily wastewater, and radioactive wastewater has also been studied. [14][15][16][17][18][19] SIE performance is primarily determined by two indicators: evaporation rate and evaporation efficiency.…”
