Efficient solar-powered evaporator with multifunctional nanofiber

Interfacial solar steam generation is acknowledged as an extremely effective and environmentally friendly method of producing potable water. Nevertheless, significant challenges persist in the development of an evaporator capable of achieving heightened rates of evaporation, catalytic capabilities, resistance to bacterial proliferation, and effective light absorption across a broad spectrum. This article outlines the fabrication of a solar steam generator utilizing electrospinning technology and membrane evaporators constructed from α-Fe2O3/PAN (polyacrylonitrile) nanofibers. The integration of α-Fe2O3/PAN composite enhances both light absorption and heat generation. In sunlight, the maximum evaporation rate is 2.7 kg m−2 h−1, which is significantly more than the rate of today's cutting-edge solution-electrospun nanofiber-based evaporators. The electrospun mat has high catalytic activity and antibacterial properties, making it an important component in desalination.
