Solar evaporative desalination technology is one of the most promising technologies to alleviate freshwater shortages, but the preparation of an inexpensive and sustainable 3D substrate remains a challenge. Lignocellulosic sponge (LS) is a commercial product that is widely available, clean, renewable, degradable, inexpensive, and porous. In this work, LS was found to be a good substrate for photothermal evaporation. LS has good compatibility with polypyrrole (PPy), which has excellent photothermal conversion performance. A simple and effective photothermal conversion evaporator (PPy-LS) was obtained by in situ polymerization of pyrrole on the surface of LS by chemical oxidation. The as-prepared PPy-LS exhibited good light absorption and thermal management capabilities, possessing an evaporation rate of 1.85 kg m −2 h −1 and an evaporation efficiency of 88.65% at 1 sunlight. PPy-LS also had excellent mechanical properties, superhydrophilicity, and water absorption. Combined with its porous network structure, PPy-LS exhibited good salt tolerance in 10 wt % NaCl solution and excellent thermal management capability. The PPy-LS solar evaporation device has the advantages of a simple preparation method, good durability, and sustainability, which provides an important direction for solar interface evaporation.
