Abstract
The disclosure provides a solar evaporation substrate for recovering water from a solution. The substrate includes a porous support and an activated carbon-cement composite. The disclosure also provides a solar thermal evaporation apparatus based on a novel substrate. The apparatus includes an open tray, a solution, a solar evaporation substrate, an enclosure and a plurality of collectors. The disclosure further provides a method for preparing the substrate from activated carbon-cement composite coated porous support and that is used to heat the solution by harvesting solar energy. The apparatus and method is chemical free, cost effective and gives a high evaporation rate of 2.4 kg/m2 h under one-sun illumination with zero carbon footprint.
