Abstract

Ti<sub>2</sub> O<sub>3</sub> nanoparticles with high performance of photothermal conversion are demonstrated for the first time. Benefiting from the nanosize and narrow-bandgap features, the Ti<sub>2</sub> O<sub>3</sub> nanoparticles possess strong light absorption and nearly 100% internal solar-thermal conversion efficiency. Furthermore, Ti<sub>2</sub> O<sub>3</sub> -nanoparticle-based thin film shows potential use in seawater desalination and purification.
