High‐Performance Photothermal Conversion of Narrow‐Bandgap Ti 2 O 3 Nanoparticles

Ti2O3 nanoparticles with high performance of photothermal conversion are demonstrated for the first time. Benefiting from the nanosize and narrow-bandgap features, the Ti2O3 nanoparticles possess strong light absorption and nearly 100% internal solar–thermal conversion efficiency. Furthermore, Ti2O3-nanoparticle-based thin film shows potential use in seawater desalination and purification.
