An ecofriendly and efficient wood-based polyoxovanadate solar evaporation generator

Currently, freshwater scarcity is a global challenge, and developing low-cost methods for purifying, desalinating, distilling seawater crucial. Natural wood, owing to its advantages of high hydrophilicity, low density, microporous channels, thermal conductivity, widely considered vehicle solar evaporation. However, the majority reported wood-based evaporation generators have been economically inefficient, with limited rates under low-power irradiation. Herein, we developed an ecofriendly efficient generator comprising material excellent photothermal conversion efficiency, polyoxovanadate, loaded on wood surface natural channel structure. The exhibited light absorption capacity (∼98%) in wide wavelength range 200–1200 nm, rapid water transport through minimal heat dissipation due adiabaticity reduced enthalpy. Therefore, overall efficiency was increased, rate 2.23 kg m−2 h−1 solar-vapor 90% 1 Sun observed. This environment-friendly, low-cost, high-efficiency has enormous potential practical applications desalination purification.
