Interfacial solar desalination is an emerging technology for freshwater production,but the finding of novel solar evaporators is still *** the present research,graphitic carbon foam(CF)was synthesized from the upcycling of waste plastic polyethylene terephthalate(PET)waste bottles functionalized with carrollite CuCo_(2)S_(4) as a photothermal *** characterization[X-ray diffraction(XRD),Fourier transform infrared spectroscopy(FTIR),and scanning electron microscopy-energy dispersive spectroscopy(SEM-EDS)]confirms the functionalization of carrollite CuCo_(2)S_(4) on graphitic carbon *** UV-Vis spectroscopy analysis showed an enhanced optical absorption in the UV-Vis-near IR region(>96%)for functionalized CuCo_(2)S_(4)-CF foam compared to carbon foam(67%).The interfacial solar desalination experiment presented a significantly enhanced evaporation rate of 2.4 kg·m^(−2)·h^(−1) for CuCo_(2)S_(4)-CF compared to that of CF(1.60 kg·m^(−2)·h^(−1))and that of CuCo_(2)S_(4)(1.60 kg·m^(−2)·h^(−1)).The obtained results proved that the newly synthesized CuCo_(2)S_(4)-CF from the upcycled plastic into new material for the photothermal desalination process can enhance the practice of a circular economy to produce fresh water.
