Fig. 2: The photocatalytic and photothermal properties of Ti₃C₂T_x, Bi₂S₃, Bi₂S₃/Ti₃C₂T_x-2, Bi₂S₃/Ti₃C₂T_x-5, Bi₂S₃/Ti₃C₂T_x-7, and Bi₂S₃/Ti₃C₂T_x-10.

a ROS production with DCFH fluorescence probe (200 ppm). Data are presented as mean ± standard deviations from a representative experiment (n = 3 independent samples). b Photocurrent response under 808 nm NIR irradiation. c PL spectra tested with 325 nm excitation wavelength from 350 nm to 600 nm. d EIS tests with or without 808 nm irradiation. e Photothermal curves of different samples under 10 min light (808 nm) irradiation. f Temperature rising and cooling profiles of Bi₂S₃/Ti₃C₂T_x-5 when the irradiation is on/off under 808 nm. Source data are provided as a Source Data file.
