Super hydrophilic biochar-based hydrogel with tunable aqueous state for efficient solar-powered desalination - ScienceDirect

[Michael Hayes]

Highlights

• •
  Biochar-based hydrogels with tunable aqueous states were successfully synthesized.
• •
  Evaporation rate hit 1.8 kg m-2h−1 with 89 % photothermal conversion efficiency.
• •
  After 7 days, SGG-PEG0.3 still gave an evaporation rate of 1.71 kg m-2h−1.
• •
  Post 7 days, SGG-PEG0.3 still retained 83.73 % photothermal conversion efficiency.
• •
  Outdoor evaporation experiments collected up to 8.89 kg m−2 of water a day.
