Hydrophobic CuSbS-deposited photothermal film for interfacial water evaporation and thermal antibacterial activity

Hydrophobic Cu 12 Sb 4 S 13 nanoparticles with strong and full-spectrum photoabsorption in the range of 200-2500 nm were fabricated and deposited on cellulose acetate (CA) membrane to form a photothermal film, which could realize photothermal heating for vapor generation and thermodestruction of pathogenic bacteria of E. coli O157:H7 simultaneously under light irradiation. Cu 12 Sb 4 S 13 photothermal film realized interfacial water evaporation, simulation of solar salt formation, and thermal antibacterial activity simultaneously.
