Solar Driven Interfacial Steam Generation Derived from Biodegradable Luffa Sponge

A chemically treated luffa sponge (LS) derived from the ripe fruit of Luffa cylindrica (LC) plant is investigated as an efficient solar photothermal conversion material for water purification applications very first time. Hydrophilicity and absorbance LS are enhanced by dopamine treatment candle soot surface coating. The fabricated modified (SM-LS) leads to a superb evaporation rate high 1.30 kg m−2 h−1, which five times higher than that freshwater under 1 sun illumination. outdoor experiment shows excellent efficiency 79.98%, significantly other low-cost materials. Such SM-LS can be further applied desalinate seawater, where it shown m2 surface-modified produce 7.5–8 L per day. Hence, proposed system utilized in remote areas refugee camps.
