Seawater desalination performances of a Janus VOPM with a thermal insulator. (a) Weight loss and evaporation rate of water as a function of irradiation time under one-sun illumination. (b) Ion concentrations of seawater before and after desalination. Red balls refer to the calculated rejection ratios of ions.
