Abstract
- Using solar energy for freshwater generation presents an effective and economical solution to address water shortages. Here, we introduced a structural strategy involving the incorporation of fixed-shape inverted pyramid-shaped grooves onto the evaporator surface. This innovation approach integrated delignified wood and MXene-based photothermal material to establish an interfacial solar steam generator (ISSG) dedicated to freshwater production. The carefully designed surface structure empowered the ISSG with remarkable heat localization capabilities, resulting in an exceptional steam generation capacity and resistance against salt deposition. The as-prepared sample, labeled MIDW-5, achieved an impressive evaporation rate of 1.927 kg m−2 h−1. Furthermore, the simulation results by COMSOL are in agreement with the experimental results. Therefore, the incorporation of MXene into delignified wood, complemented by the imprinted structure, yields a high-performance evaporator with substantial potential for low-cost freshwater production. • A MXene@wood evaporator with inverted pyramid-shaped grooves was constructed. • The evaporator has excellent thermal localization efficiency. • The evaporator shows splendid high light absorption and evaporate rate. • The evaporator is easy to prepare and environmentally friendly. • The evaporator performs outstanding desalting performance.
