High-Performance Photothermal Conversion of Narrow-Bandgap Ti2 O3 Nanoparticles

Adv Mater. 2017 Jan;29(3). doi: 10.1002/adma.201603730. Epub 2016 Nov 11.


Ti2 O3 nanoparticles with high performance of photothermal conversion are demonstrated for the first time. Benefiting from the nanosize and narrow-bandgap features, the Ti2 O3 nanoparticles possess strong light absorption and nearly 100% internal solar-thermal conversion efficiency. Furthermore, Ti2 O3 -nanoparticle-based thin film shows potential use in seawater desalination and purification.
