Abstract:Solar water evaporation is an effective solution for
water desalination
without the energy use of secondary energy or fossil fuels. A ferric
tannate (TA-Fe3+)/sodium alginate (SA-Fe3+)/polyacrylamide
(TFSFP) hydrogel was synthesized and constructed as a solar water
evaporator (SWE). Tannic acid (TA) and Fe3+ was chelated
in situ through a convenient method combined with the cross-linking
of SA. Along with an ion cross-linked SA-Fe3+ network,
a porous hydrogel with a hydrophilic water transportation network
