AI Technical Summary
Existing plasma metal materials for seawater desalination suffer from narrow absorption spectra, poor chemical and thermal stability, and high costs. Furthermore, traditional photothermal material fixing methods result in low evaporation efficiency and easy scaling.
The rare earth-based wood-based solar water purifier uses modified natural wood as a base and rare earth boride nanocrystals as a light absorption layer. It utilizes the local surface plasmon resonance characteristics to achieve full-spectrum light absorption and optimizes water transport and heat management through a three-dimensional porous structure.
It achieves efficient light absorption and photothermal conversion across the entire spectrum, improves water evaporation efficiency, reduces heat loss, and possesses long-term stability and low cost. It also features multi-functional integration of seawater desalination, wastewater purification, and disinfection.
