Figure 3. (A) Extinction spectra of MXene, Bi₂Se₃, and MXene/Bi₂Se₃. (B) Photothermal curves of the solution (25 μg mL^-1) under 808 nm (1.0 W cm^-2) laser irradiation. (The solid line represents data from a single test, while the shaded area indicate the error bands (SD) derived from three replicate tests. (3) of the corresponding sample by row statistics method). (C) Thermal images of DI water, Bi₂Se₃, and MXene/Bi₂Se₃. The heating and cooling curve of Bi₂Se₃ (D) and MXene/Bi₂Se₃ (E). (F) Cyclic test of photothermal curves of MXene/Bi₂Se₃ (1:5).
