The delamination of titanium carbide sheets, anintriguing class of two-dimensional materials, has been criticallydependent on the extraction of interlayer Al in acidicmedia, such as concentrated hydrofluoric acid (HF) ora mixture of hydrochloric acid (HCl) and a fluoride salt. Herein, we report an organic-base-driven intercalation anddelamination of titanium carbide that takes advantage of theamphoteric nature of interlayer Al. The resulting aluminumoxoanion-functionalized titanium carbide sheets manifestedunusually strong optical absorption in the near-infrared (NIR)region with a mass extinction coefficient as high as 29.1 Lg^-1cm^-1 at 808 nm. Thus, the performance of thismaterial is comparable or even superior to that of state-of-the-art photoabsorption materials, including gold-based nanostructures, carbon-based materials, and transition-metal dichalcogenides. Preliminary studies show that the titanium carbidesheets serve as efficient photothermal agents against tumorcells.
