Integrated solar seawater desalination and power generation via plasmonic sawdust-derived biochar: Waste to wealth

Silver sulfide decorated carbonaceous sawdust/ES-PANI composites as salt-resistant solar steam generator

“…Carbonized wood exhibited just one wide diffraction peak at 22°, which may also be seen in Ag 2 S@PANI/CW XRD patterns with low intensity. 51 In addition, three diffraction peaks were seen in pure PANI, corresponding to semi-crystalline planes (011), (020), and (200) which were found at 15.2°, 20°, and 25.3°, respectively. 54,55 Furthermore, Ag 2 S@PANI/CW also revealed that the crystal plane and diffraction peaks of Ag 2 S were found at 25.3° (110), 28.9° (111), 32.3° (−112), 33.6° (120), 37.9° (−103), 40.7° (031), 44.4° (103), 46.7° (−123), 51.2° (−221), 54.8° (041), and 64.4° (−134).…”

“…While the band at 2931 and 2850 cm −1 represents C–C. 50,51 The high intensity of the absorption band of phenolic and alcoholic hydroxyl groups is due to the lower pyrolysis temperature. For PANI, the peaks at ∼1560 and 1480 cm −1 correspond to the quinonoid and benzenoid rings CC stretching, respectively.…”

“…Because of its porous nature, CW has good optical properties, improving multi-scattering-induced light trapping, lowering light transmittance, and lowering light reflection to the surrounding. 51 Furthermore, PANI provides even more value to the composite due to its unique photothermal conversion capacity, high adhesive qualities, and good hydrophilicity. In addition, the performance of solar evaporation was evaluated by determining the evaporation rate and evaporation efficiency under one solar illumination ( Fig.…”

“…The FT-IR spectrum of CW showed several bands at 3381, 1734, 1596, and 1029 cm −1 correspond to strong hydrogen-bonded O-H, C]O, C]C, and C-O. While the band at 2931 and 2850 cm −1 represents C-C. 50,51 The high intensity of the absorption band of phenolic and alcoholic hydroxyl groups is due to the lower pyrolysis temperature. For PANI, the peaks at $1560 and 1480 cm −1 correspond to the quinonoid and benzenoid rings C]C stretching, respectively.…”

Solar-driven seawater desalination via plasmonic hybrid MOF/polymer and its antibacterial activity

“…Aer radiation was switched off, the salt on the evaporator started to dissolve back into the bulk brine aer a long time, showing saltrejection performance. [95][96][97][98] In Fig. 4c, the solar evaporation performance was shown by evaporation efficiency and the evaporation rate under 1 sun.…”
