Potentially scalable fabrication of salt-rejection evaporator based on electrogenerated polypyrrole-coated nickel foam for efficient solar steam generation

Solar steam generation (SSG) is a green and sustainable way for desalination. Herein, we report for the first time the electrodeposition fabrication of bilayer photothermal material (named PPy-NF-PUS) for efficient desalination, which was prepared by electrodeposited polypyrrole on nickel foam (PPy-NF) as the upper layer for solar absorption and polyurethane sponge (PUS) as the lower layer for water pumping and thermally insulating.
