Figure 11. (A) Wavelength-dependent AQYs vs. the corresponding UV-vis DRS spectra of the pristine Ti₃C₂T_x and S-Ti₃C₂T_x (Ti:S = 1:8) catalysts; (B) Time-resolved transient PL emission decay of the pristine Ti₃C₂T_x and the S-Ti₃C₂T_x (Ti:S = 1:8); (C) The comparison of gas yields under different focused sunlight without or with temperature control (T = 293 K) using the pristine and the S-Ti₃C₂T_x (Ti:S = 1:8); (D) The photo of solar energy stove reactor without T control; (E) The comparison of gas yields under different focused incident sunlight (different dates) using the S-Ti₃C₂T_x (Ti:S = 1:8); (F) The photo of solar energy stove reactor with temperature control at T = 293 K under the focused sunlight; (G) The comparison of STF is measured at different dates using the S-Ti₃C₂T_x (Ti:S = 1:8).
