Summary: A bionic hydrogel-aerogel composite evaporator with a respiratory root structure was proposed in this study. By constructing numerous vapor escape channels, the evaporator achieved a high evaporation rate of 2.7 kg m-2h-1, which is twice that of most salt-resistant evaporators. This design significantly improves the evaporation rate when resistant to salt accumulation, providing a novel strategy for developing highly efficient, long-term stable solar interfacial evaporators.

Summary: Water hyacinth can invade and harm aquatic ecosystems, but its derived carbon can be used for various applications, such as removing oil spills and desalination. In this research, lignocellulose aerogels from water hyacinth were transformed into carbon aerogels and activated carbon aerogels. The desalination capacity of the MCDI device using the activated carbon aerogel electrode was evaluated, achieving a high salt adsorption capacity of 14.69 mg g(-1) after 3000 s. These findings open up a new research area for converting biomass and bio-waste into CDI-utilized carbon aerogel electrodes.
